so I've decided to add another band to my stable. I auditioned last night with a group doing largely 80s covers. It's a 4 piece: drums, guitar, vox and bass. The vox are strong, the drummer is fantastic and the guitar is above average. Their are targeting small corporate and event gigs. Where it gets interesting is that they heavily utilize backing tracks for keys, percussion and even some backing vocals. Drummer plays to a click to keep us in time to the track. The tracks are reasonably well done and the musicians blend pretty well. They've still got some cleanup to do, though, especially on levels. And some of the tracks are a bit over done. At this point they've offered me the slot. I've never done backing tracks like this before, and I'm questioning how marketable and acceptable this will be. Have any of you ever used them, and how was it received?
