I saw this group in concert in 1969 at the Denver show with other bands, Big Mama Thorton, Frank Zappa and Three Dog Night. I wasn't high, stoned or drunk, and this band blew me away, especially with the really long rendition of In-A-Gadda-Da-Vida, like 30+ minutes.
Well, I've never forgotten them or this album I bought a few months later when I had a stereo system to play. I was in technical training at Lowry AFB in Denver, Colorado before being assigned to McClellan AFB in Sacramento, California. The concert was in the old Denver stadium about where Mile High Stadium is today. The accoustics were all that great but no one minded.
We attended the Friday concert and the next night the concert had a fight with erupted into a riot and closed the concert. The Sunday afternoon concert went better. But the Friday concert was great, outside of the occasional individual being too far gone to realize where they were and needed to be helped or escorted out of the crowd.
We had good seats and stayed the whole time getting back to the barricks well into early morning. After that what can I say, I was 19 years old, it was 1969, and music was cool. And they were awesome. And for what it's worth, Erik Braun, one of the guitar players, was a violin prodigy before playing the guitar. And folks then thought rock musicians were self-taught, garage practicing players.
It's always a turn-up-the-volume album and ... the neighbors music. Even now in my 60's.
