Mine is a war-forged who had speakers built into him.

 I had a goblin bard. Who was pretending to be a rock gnome. With help of bard skills and being an “actor”. Rather than be the goblin “Fork” he was “Tanrug Twinkletongue”. He did this to avoid goblin persecution and genocide, and other less desirable living situations as a result of being a goblin.

(college of whispers)

 It's saddening when more good natured  goblins get persecuted for being goblins. *grabs droop from lost mines of phindelver*

15 whisper bard / 5 assassin rogue

Not sure it's exactly creative, but I have a Lightfoot Halfling Bard named Gordon Lightfoot (he is known as "The Minstrel of the Dawn"). 

My bard is a Locath named Blimz who is a famed performer in Locath coloneys in Saltmarsh, but is better known for his clam chowder. A food critic tells him he needs more "landy" spices, so he sets out to find anything "landy" to put in to his chowder. Here is the full backstory:

"Blimz was, by all accounts, a masterful bard. His lute, crafted from the shell of a giant crab, sang with a melody that could calm a kraken's rage. His voice could shatter barnacles and woo even the most stoic sea elves. His jokes were so sharp, so perfectly timed, that they were known to make pufferfish explode with laughter. He was the undisputed star of Saltmarsh's underwater variety shows.
Yet, there was one thing that outshone even his most dazzling performances: his clam chowder. A secret recipe, passed down through generations, his chowder was so good it was rumored to make the merfolk weep with joy and the locath forget their eternal rivalry with the lizardfolk. It was a sensory experience that transcended all others.
The trouble started when a pompous sea elf, a renowned food critic, came to Saltmarsh. He tasted Blimz's chowder, and his mind was blown. He declared it "the most perfect clam chowder ever to grace the ocean." This, however, came with a caveat. "It is missing one thing," the critic announced, "a flavor from the surface world. A pinch of something… landy."
Blimz was heartbroken. He had mastered every ingredient the ocean had to offer, but he couldn't find a single "land" spice. The shame was too much to bear. So, he made a decision. He would journey to the surface world. He would find the most exotic, most flavorful, most "landy" ingredient in all the realms. He would return a hero, his chowder an undisputed masterpiece. His goal is simple: find the perfect ingredient to complete his chowder recipe and solidify his place as the greatest chef in all of existence. He has no idea what he's looking for, but he's sure to find it, one "landy" ingredient at a time."

First, I noticed a mention of Droop. I LOVE DROOP! Lost Mine of Phandelver was my first campaign and my party literally recruited Droop and gave him a home, equipment, a paycheck, and an apprenticeship at the Emerald Enclave. I thought it was heartwarming so I gave Droop class levels as an Illusionist Wizard and made him their little sidekick buddy as a reward.

And to answer the actual question:
Tiefling Bard of Valor.
He hates that Tieflings are almost universally hated and set out to be a hero to prove everyone wrong. But Tieflings have tried that before and it never worked, so Truth got smart. He pretended to be a different person with every adventure, but always a Tiefling. The idea being, if he did lots of heroic things and made it look like many different Tieflings did heroic things, he could convince others that most Tieflings are in fact good people. He uses a new alter-ego every adventure arc, so he's never boring to play. Because he's a Bard of Valor, he's good at support, aggressive magic, enchantments, and weaponry. So far, he's pretended to be a quirky wizard using divination, a gruff rogue, a stoic and humorless fighter, and a wise and helpful cleric. His true personality is totally hidden from others, it can be whatever you want.

Other good subclasses for this concept are College of Lore if you want more spells and College of Masks for more alter-ego inspiration.
Other good species include drow, orcs, and goblins.

Feel free to use this character concept!

This concept is actually for a Bladesinger, but could totally also be a Bard.

Lazuli the Earth Genasi
She peers into the future a lot, but when she does she forsees concerts from famous pop stars in the 21st Century. She uses illusions to make her performances even more stunning and also to loudly blast pop music. Every time a combat begins, I choose another pop song for her to play and I theme her battle strategy around it.
I just picked Earth Genasi because I think they're cool. She would probably make more sense as a human anyways.

A dwarven bard who played the anvil.

It wasn't a true anvil but was an 'anvil shaped object' that was shaped and tempered for the purpose of producing various tones as it was struck. Nevertheless, it was played with a pair of metal hammers (that were wielded as light hammers in combat) and weighed 50 lbs.

I have a radio themed College of Lore Bard. He works as a radio salesman, reporter, and Radio show host. He practically invented the common Radio in this universe, because at this point only really the military or government Establishments used it. He was going to get it mass produced by factories and big businesses,  but realized it would likely be used for propaganda, Scams, and manipulation. Using his skills in tinkering, he makes and sells small, portable radios. He sells them not for profit; he sells them to spread truth, as he works as an Oracle of Savras (God of Truth). He's a haregon, to work as a pun on "Rabbit Ears" with that being CB radio slang for either the antenna on a truck, or if someone is listening in on a Radio channel, something He's very good at.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            

Hollie Shuvit the College of Dance Bard

He's a harengon that was present in the Feywild and invented skateboarding, though the furious Fey Frænk Jor'dan placed a powerful fey curse on Hollie to steal his invention before kicking him out of the Feywild. Now, he travels the land trying to piece back his invention and hopefully get his revenge on Frænk.

Another player has a fellow harengon bard (Clover) that provides some nice company to Hollie, which is pretty cute

College of Spirits Verdan Bard.

She once was a part of a heroic adventuring party. She loved them so much, they were basically her family. But then one day she was swallowed up by the Mists. After that, she wandered the Mists, enduring the horrors of Ravenloft. Finally, after four very long and painful years, she was spat back out by the Mists and was free! But she found herself in the wrong place. Specifically the Forgotten Realms.

Unfortunately, she suffered amnesia. She forgot all of her exploits in her original world, and she doesn't even know what her original world is. She only knows her name. And that she had a family once. Her former party, but she doesn't know that. Whenever she uses her Tales from Beyond, it's not a random spirit giving her powers. It's a hollow, faded memory of one member of her former party, briefly being remembered and then forgotten again once the power is used.

These "former party members" are actually characters that my friends have used. I just referenced them when I created this character.
