My Google-fu is weak. I'm getting back into playing guitar and want to mess around with GarageBand to record some cover tracks. I play guitar and bass, but need pre-recorded drump tracks for classic rock songs (AC/DC, Rush, Zeppelin, etc.). After Googling, the best option I can seem to come up with is recording a drum track from Songsterr with everything muted but the drum tracks and pumping that into GarageBand. I realize doing this I'm not going to get the best sounding drums, but at least I'll get a steady rhythm for learning the songs and messing around recording. So, my question is: what are people who do similar recording/learning using for drum tracks?
