Birch''s Backing Tracks sells a variety of Multitracks, Backing Tracks and Seperate Instrument Tracks. The Multitracks contain seperable tracks of the different instruments in the song. Backing Tracks are basically a version of the song that has one instrument taken out for you to play along to, and seperate instrument tracks are basically self explanatory. At the moment our range only covers the rock/metal genre, but we are willing to expand. We are also the cheapest Multitrack supplier on the net. So we should be your top choice!
