I've always preferred their shorter tracks, especially those on albums like American Beauty. I think they produced relatively little of merit since c. 1974, virtually everything I liked from them dates from before that. However, their jams did influence every subsequent jam band. Personal favorites include:" Rosemary," "Ripple," "Box of Rain," St. Stephen," "The Golden Road," "Bertha," U.S. Blues," etc. They are an exception to my usual rule about the worth of a band in that their best known and overplayed tunes tend to be the best ones.
