Many of you probably already know of them, but I think they are such an underrated band. Play mostly in the southern Cali area where they are from.
Just listen to the first song and decide. It's not even my favorite or anything, but I think it shows how elastic a jamband they are. Just a fun dance groove to so many of their tunes, I think most deadheads would enjoy them if they gave them a chance.
If you just want to sample from below try Shape Shifter, BBQ and Walls of Jericho
