My band is Symphonic-ish Death Metal. So my lead guitar player quit recently. We have a show this weekend in Toronto. We use backing tracks for strings/piano/synth/samples live. I play guitar and do vocals, and we have a bass player now. My drummer thinks we should add the departed guitarist's album rhythm AND solos to the backing tracks, and use that live. I could just run a stereo rig with 2 amps/cabs and delay 1 side by 20ms so it sorta sounds like 2 guitars. I think it would work fine. Our guitar parts are very different and really compliment each other. He and I rarely ever played the same riff. He liked to harmonize my parts, etc so it sounds a little different/lacking now. I realize that most audience members won't have a clue what is real guitar and what is backing track... We're also a lesser known band, so I get that no one at the bar will have heard our music before either... I'm not interested in cancelling shows and shutting down until another guitarist can be found. I saw a band live recently that had backing tracks with dissonant-meshuggah-style-background-guitars and lo-fi guitar parts and synth tracks and it seemed a little much! tldr: Should we play live with just 1 guitar, or play his album tracks to fill in his parts?? What do you think?
