here's a "Dark Hollow" backing track for practicing to: no vocals and only bass & drums on the solo sections. i doubled the length of the second solo section before the outro (last chorus)... recording process was 1) started with the bongos as a "live click" track 2) added the electric bass guitar (tuned EADGC) 3) added the electric guitar track (tuned ADGCF)... mixed in Audacity. no metronome, quantization, looping, stretching, chopping, time-stretching/warping, etc. was used.
