If you like Super Mario, you will enjoy this video. This boy plays the music for the game on a violin, while someone else is playing. He makes all the sounds: jumping, getting coins, killing the bad guys, everything!
The next clip takes multitasking to a new level. The man, Adam Winrich, is playing the guitar and the harmonica simultaneously. He even said that he uses his harmonica to add so some of the guitar chords!
These two Polish men can't get no satisfaction. They are in Oslo, Norway and they use bottles to whistle the song Satisfaction by the Rolling Stones!
