Great jazz/prog/rock
It seems that many more European bands were willing to embrace the exploratory spirit of "Bitches Brew" than American ones....or maybe the American labels just weren't willing to open the doors. "Opal" by Embryo is a fine early example of the successful fusion of jazz and rock that is willing to play it heavy in either direction with the occasional stop along the way to feed on your brain. The violin gives it a "Snafu" era East of Eden feel and the interplay between guitar and horn brings to mind one of my favorite bands in this genre: Burnin Red Ivanhoe.Fans of the aforementioned bands and the free spirited early sides of Amon Duul,Amon Duul II and Gong will enjoy.
