I've got a few of buddies around here who gig pretty much exclusively with a looper, especially in these Black Plague 2.0 times. A couple of them are guitar picker/singer types, and one dude is an EXTREMELY talented multi instrumentalist (Sax, EWI, guitar, bass). Before lockdown I would go see them playing around, and the necessity of every tune having a 2-3 minute buildup of the background elements before the actual SONG started, for me at least, got a little old after a while. I found myself coming away from the performance more admiring how clever the concept was rather than how great the musical experience was....I think in small doses interspersed throughout the evening it comes off better.....
