Jack was a treasure and his guitar work with Jill providing vocals was a real pleasure for years
We wanted to take a moment to acknowledge the tragic passing of jazz and avant-garde guitarist Jack Grassel last week. When we were kids in the 1970s, our moms would drop us off at the Wisconsin Conservatory of Music to see him perform as part of a duo with drummer Dave Ruetz — who happened to be Jay's drum teacher, and our way into finding Jack in the first place.
We'll never forget one of those shows when Jack stopped mid-set and said, "I'm not really a rock guitarist, but I do appreciate the things that Jimi Hendrix did for the instrument." And with that, he and Dave launched into a out-of-left-field version of Purple Haze. That was Jack — technically a jazz and avant-garde guy through and through, but always ready to blow your idea of what he was "supposed" to play.
Years later, when Jay was working at Record Head, Jack would pop in now and then to talk music and gear with the staff. Decades later, Jay sent him a copy of our song "The Pack is Back." Jack wrote back: "Excellent Music." Two words from a guy like that meant more than we probably let on at the time.
More recently, Jack and his wife Jill Jensen started inviting Jay and other friends over to their home for small, informal concerts they'd play — Jack still finding new ways to make and share music, sometimes on instruments he'd built himself, including a triple-necked guitar/bass/mandolin hybrid of his own invention.
Jack was a fixture of Milwaukee music for over 50 years, from his days in the genre-bending 1970s group What on Earth? to decades teaching at MATC. But for us, he'll always be that guy on the Conservatory stage tearing into Purple Haze, then the guy who wandered into a record store just to talk shop.
Watching Jack and Dave up there all those years ago planted something in both of us that never really left — you can probably trace a straight line from those Conservatory afternoons to every stage Couch Flambeau has ever played. Thank you for showing us what it looked like to spend a whole life chasing the sound.
