wolf_garcia - They established the "jam band" concept so there's that, and were a zero downbeat cruise feel…some great musicianship though, and the 2 studio albums "Workingman's Dead" and "American Beauty" were fabulous.+1
I'll add that their live recorded music music is among the best IF NOT THE BEST quality from an overall resulting sound perspective. The vast majority of their shows are available in multiple mix type soundboards, front of board audience tapes by tapers who were allowed and encouraged to bring the best-of-the-best recording gear , syndicated radio shows where the music was professionally mixed and remastered ie. Grateful Dead hour hello shout out to David Gans / sonic solutions, and on and on.... DEAD-ication to sound quality and excellence... a band beyond description ......
