I often think of the Art Ensemble of Chicago descriptor: “Great Black Music-Ancient to the Future”, as an unending river of sound, fed by thousands of musicians, known and unknown, who have devoted their lives to elevating the magic property of music. We are all part of this immense unfolding history that is deep and powerful. Dimensionality, the band we heard on October 3, is one important musical drop in that glorious bucket. The quartet: Andrea Wolper (voice), Ursel Schlicht (piano), Ken Filiano (bass), and Lou Grassi (drums), filled the big barn at the Institute For the Musical Arts in Goshen, MA with a creative spirit inspired by the late pianist Connie Crothers.
Artists are tasked with using the vast reservoir of previously made music to create something new, something of their own making. Dimensionality channeled Crothers’ originality and spontaneity, evoking her essence without quoting her directly.
When Crothers first heard Lennie Tristano’s “Requiem”, she dropped her music education at UC Berkeley and moved to New York to study with him. And even though she built her own identity as a player and composer, she remained deeply committed to his work for the rest of her life. As Giovanni Russonello wrote in his NY Times obituary, Crothers, like Tristano, possessed “a densely layered pianism and a faith in free improvisation.” In addition to having two dozen recordings as a leader (including a duo with Max Roach), and concert appearances around the world, Crothers was a dearly valued mentor and friend to many. “She supported so many people by going to their gigs, encouraging them, connecting musicians to other musicians, advocating for musicians,” Andrea Wolper recalled in the obit.
Dimensionality formed in 2017, a year after Crothers’ death, to pay honor and keep her spirit alive. The ensemble’s first performances were at German jazz festivals in Göttingen and Schlicht’s hometown of Kassel. While Schlicht was the driving force behind the formation of the project, the band operates as a collective, and, in fact, Wolper served as the point person for this Jazz Shares concert.
Much of the music was freely improvised. It was open, and open-hearted, and had a narrative quality that carried me along. Wolper split her time between an impressive variety of mouth sounds and lyrics by herself, Kenneth Rexroth and others. An actress, activist, author and poet, Wolper has found joy improvising with people like Jay Clayton, Frank London, Vinny Golia and William Parker. In fact, Wolper and Filiano are on Parker’s brand new collection of songs: Waltz For Gregory. Wolper exuded a quiet assurance, and her surefooted note choices and sense of time made clear we were in the presence of a true professional.
Her husband and long-time musical partner Ken Filiano is a regular Valley visitor, whose last area performance was with Bill Lowe’s Signifyin’ Natives octet in 2021. The bassist has overcome loss of hearing in his left ear and loss of function in his right hand, which required surgery almost a year ago. We’re glad he is back on the scene, because his infectious positivity has impact both on and off the bandstand. He was his usual masterful self, and his use of electronics added layers to the sound palette. Closing my eyes eliminated the distraction of watching his gear fiddling, and allowed me to focus on the complexity and beauty of his contributions.
Lou Grassi is an athletic 79 year old with unerring touch. His unaccompanied solo statement, which introduced one of the pieces, began with him playing two flexatones, a 1920’s invention consisting of two wooden balls striking a sheet of metal. The sound, which can be bent by applying thumb pressure on the metal, is familiar to consumers of classic cartoons, and brought waves of smiles and chuckles from the assembled. Like he did with his table of rattles and IMA’s vintage Craviotto drum kit, Grassi made music with the flexatones. As he kicked the band into an exuberant groove, I was reminded of Gary Giddins’s observation: “Swing is liberating only when it’s an option; if someone tells you to swing or else, it’s tyranny.”
Ursel Schlicht, who lived in New York from 1995-2013, studied with and conducted extensive interviews with Crothers, and wrote about it as part of her book on female jazz musicians, It’s Gotta Be Music First. Schlicht was instrumental in helping the ensemble achieve what Crothers called “band merge”. She received the Hessian Jazz Prize in 2025 for innovative playing, intercultural projects and commitment to equality in jazz. Now that her children are finishing high school, Schlicht should have more time to “play out” in Europe and the States.
“It’s dimensional”, Crothers used to say about making creative music. On this tenth anniversary of her passing, Dimensionality is proudly advancing Connie Crothers’ legacy, taking the music to Rochester, NY (BopShop) and Ann Arbor, MI (Edgefest) in the coming days, adding to the great river of sound.
