Desktop music-mixing software like GarageBand has liberated musicians from the sound studio. Now Bojam wants to liberate them from the constraints of geography or the isolation of their rooms. Bojam is a Web-based sound studio that lets musicians practice playing music, find other musicians around the world to jam with, and lay down tracks together on the same song. Bojam is a fully functional music mixer. You can adjust the volume on each track or add effects like distortion and reverb. CEO Andrew Greenstein claims that Bojam has "all the advanced features you would find in a studio recording mixer, but all on your browser." During the demo at TechCrunch50, he showed how a drummer in LA, a bassist in Tel Aviv, and a keyboardist in Tokyo recorded a song together on Bojam. (Unfortunately, the song they chose was Toto's "Africa").
