When you're running a label, a demo occasionally comes across your desk that makes you reconsider everything you thought your label was all about. For Balmat, such was the case with this stunning album from Stephen Vitiello, Brendan Canty, and Hahn Rowe. It sounds like nothing Balmat has released so far. Fans of ambient, experimental electronic music, and sound art will be familiar with Vitiello, a New York native, long based in Virginia, who has collaborated with a cross-generational list of greats: Taylor Deupree, Steve Roden, Lawrence English, Tetsu Inoue, Nam June Paik, Ryuichi Sakamoto, Pauline Oliveros, and many more. This album is something different. It may begin in ambient-adjacent territory, but it quickly veers off, and it just keeps zigzagging, taking on elements of krautrock, post-punk, dub, and the groove-heavy interplay of groups like Natural Information Society and 75 Dollar Bill. This stylistic turn is thanks in large part to Vitiello's choice of collaborators. Active since the early 1980s, Rowe -- a violinist, guitarist, and producer/engineer -- has played with, or manned the boards for, a frankly jaw-dropping list of musicians: Herbie Hancock, Gil Scott-Heron, the Last Poets, Roy Ayers, John Zorn, Glenn Branca, Swans, Live Skull, Brian Eno, David Byrne, Anohni, R.E.M., Yoko Ono, and many more. Canty, of course, is the legendary drummer of Fugazi, the visionary DC post-hardcore group, as well as Rites of Spring before them, and, currently, the Messthetics, a Dischord-signed instrumental trio with guitarist Anthony Pirog and Fugazi bassist Joe Lally. Second took shape in phases, shifting between improvisation and collage. Vitiello laid down the skeleton of the music at home, sketching out initial ideas on Rhodes keyboard and acoustic and electric guitar; he then fed the parts through samplers and his modular system, recording 10- or 20-minute jams. Once he had edited them into more structured forms, he hit the studio with Canty, who added not just drums but also bass and piano; finally, Vitiello took the results of those sessions to Rowe, who played violin, viola, electric bass, and 12-string acoustic and bowed electric guitar, and assisted in some of the final structuring and mixdown. A few more surprises along the way: Reanimator's Don Godwin, the studio engineer where Vitiello recorded with Canty, contributed what he calls "resonant dustpan;" and none other than Animal Collective's Geologist, who just happened to be in the studio that day, sits in on hurdy gurdy. An unexpected gift is a great way of describing Second as a whole: three veteran musicians venturing outside their usual zones and finding a new collaborative language together.
