You may only know Jimmy Herring as a guitarist for Widespread Panic, The Dead and The Allman Brothers, but years earlier he founded Aquarium Rescue Unit, more of a twisted freak-jazz outfit than a jam band. His solo material reflects those roots more than it does the music of his recent sideman gigs. Herring’s new album Subject to Change Without Notice is an amalgamation of jazz, blues and psychedelic rock that despite his prodigious chops never loses sight of the music. Think a Southern-fried John Scofield. Live, he’s a badass — I’d rather see his solo act than any of his aforementioned employers, and that’s more of a compliment to him than a knock against them. Not to mention he’s got a reputation as one of the nicest, gentlest souls around, a claim to which I can attest. After my band finished an opening set for ARU in Cleveland about 20 years ago, he said, “Hey man, can I give you a hand?” — then proceeded to carry my 60-pound amp up a long flight of stairs and out to my car before setting his rig up. Needless to say, that level of generosity and humility is rare among musicians, and I’ll never forget it. You rock, Jimmy, in more ways than one.
