I agree. Happy Trails is an album you commit to listening to. You cannot just listen to a cut or two which can be done with the first. In addition of songs with lyrics dominates more of the first album and is a bit more traditional in its format. Happy Trails just blows you away, it is a very emotional album that you either get or you don't get. I grew up on the East Coast during this time period so I never did get to see them live however from my reading they were it, the SF band of choice in the beginning, not the Dead, or Airplane or Country Joe, it was Quicksilver. This however did not last.
