One Man Band is a 2005 Pixar animated short film. The short was written and directed by Andrew Jimenez and Mark Andrews and produced by Osnat Shurer, head of Pixar's Shorts group. It was shown with the theatrical release of Cars.
The short film begins with a man, named Bass, playing multiple brass instruments, and tries to get a little girl to tip him a coin, but soon meets another musician, named Treble with orchestral instruments. They both instantly become rivals and fight over the girl's coin until she accidentally drops the coin, which falls into a drain. The girl gets upset and is then angered by the two musicians causing her to lose it, and demands the two one-man-bands for a replacement coin, but they reveal that they are poor and broke. She takes one of the violins from the orchestra one-man-band, re-tuned it, and played an unexpected tune. A rich man, pleased by her performance, gives her a big bag of coins, and the girl eagerly picks it up. Before leaving, she takes two coins for the one-man-bands and tosses them into the top of a fountain, where she was originally going to put her coin in for a wish. After the credits roll, the two musicians work together in an attempt at reaching the top, where the two coins remain. As the two start to fall backwards, the short film ends.
- The music during the credits is Pablo de Sarasate's Zigeunerweisen.
- Two snare drum sounds can be heard at the beginning of Bass' fourth number (the one after the number where he balances on his snare drum). However, this should not be possible, as he never re-attached the snare drum.
