About a month ago I learned that a friend of mine is playing in a blues band that runs their gigs as a jam. Finally got to go see them last night and sat in on 5 or 6 tunes. The crowd of jammers included some relative youngsters who played with great feel. A couple guys who must have been about 30 were particularly impressive. One had a nice jazzy tone; we had some nice interplay between his guitar, my friend's guitar (more of a blues/rock thing), and my harp. The other had a bit of a country feel or sound. Both had good voices. A good drummer I worked with back in the 90s was there. No old guys who wanted to wank away endlessly on guitar solos. I was impressed.
