It’s probably reached the point where there are fans who don’t realize Henry Rollins — author, spoken word artist, soapbox raconteur, anecdotist, self-help guru, DJ, thespian, publisher, podcaster, traveler and (very importantly) human rights activist — used to be a punk/hardcore hero with Black Flag and his own The Rollins Band.

Clearly, Rollins’ brain is like one of those conical Thanksgiving cornucopias — so overstuffed that ideas and concepts tumble out for sharing. It’s been maybe 20 years since I last saw Rollins in a band context. After his show, I observed him sitting by himself on a curb behind the El ‘n’ Gee Club, having slipped out the backstage door on a chilly night, hyperventilating with expended energy, steam rising off his body like a hot water geyser at Yellowstone.

He was magnificent in his absolute commitment to his art.

On Sunday, Rollins comes to The Kate in Old Saybrook. He’s on his “Good to See You” tour, the latest of his now de rigueur spoken word junkets, so don’t expect and Black Flag or “YOU’VE GOT A LOW SELF OPINION, MANNNNN!” growls.

But DO expect to be entertained, provoked, impressed and inspired — and possibly staggered by the scope of his imagination and thoughts.

Henry Rollins, 7 p.m. Sunday, The Kate, 300 Main St., Old Saybrook; $40; thekate.org, (860) 510-0453.
