Currently there are three newer pressings of this lp available,counting the original and at least two other re-issues,that makes at least six issues of this album.Not to mention the Japanese box set complete Waters on Chess.This live album is a radical departure from his commercial recordings for chess,issued as 45's,but a more sincere take on his "club" music than his "Folksinger" album.
There is always a misprint on the album for the guitar player,it is Pat Hare,one of the gnarliest of Chicago guitar players,noted for his chainsaw tone you hear on the SUN records by James Cotton.He later murdered his wife and went to prison.Not sure what you will hear different from the various current releases,but for hardcore Blues collectors this was always a throw away session,and an indication of a softening of the Waters music.
I think that "noise" mentioned is the wind,mixing with crowd noise,as this was an outside concert near the ocean and not a subway in sight.Most of the Newport recordings were sourced from the "Voice of America" recordings for later broadcast overseas.I know that year some other labels did record albums at this festival-Columbia and Verve,but Chess would never have made these recordings as they were too cheap and lacked the initiative involved with a remote session.
Good to see people talking about Muddy,though the Newport album is not indicative,it is enjoyable and another reminder of this musical trailblazer.
