In the 80’s it was about five nights a week, the 90’s down to three (both while living in L.A.). In the 2000’s once or twice a week, these days once or twice a month. But I wouldn't call them concerts, all being in small clubs, which I much prefer. And besides, that's where the artists I want to see perform. That, and small theaters (Iris DeMent appears at The Aladdin Theater when in Portland, about as big a venue as I care for).
