Music for jamming! Send me your solo (audio or video) to firstname.lastname@example.org and I'll combine the solos and create a new track. You can download the mp3 here: longzijun.wordpress.com/2012/04/01/backing-tracks-for-improvisation-and-solos/
This is a standard 12- bar blues progression (Cm7 x 4, Fm7 x 2, Cm7 x 2, Gm7, Fm7, Cm7 x 2).
This is the first in a new series of backing tracks for your solos (guitar, saxophone, keyboards, piano, trumpet, etc). The music is free to use; just add a credit (backing track by longzijun).
The music was played on a Korg M50 (with drums loops from SoundPool). The video is screen capture of the music being played on Media Monkey with the Milkdrop music visualizer.
