I have come across what I think is the Rhino Records' box set with the recordings of the MONTEREY POP FESTIVAL on June 18 1967. It consits of 4 CD's and got I thing Substitute, Summertime Blues, Pictures of Lily, A Quick One, Happy Jack and My Generation on it. Is it any good, how is the sound quality? The shop want to have 100 dutch guilders for it ($62). theo.
