Felt Forum, New York, NY
Johnny and Edgar had earned themselves a very high status among big fans of rock music. One of my earliest guitar-playing friends just immersed himself completely in Johnny Winter when he wasn't listening to older blues men. At least for me Edgar's early 70s albums, and his incredible keyboard playing, placed him right at the cutting edge of 70s rock.
This show was so loud it was uncomfortable even in the lobby.
I don't remember it but I suppose Edgar played Frankenstein that night; I saw him play it more recently, and of course the Phish versions....
