Burnt Sugar 

For four hours, writer-musician Greg Tate and a dozen or so accomplices hunkered down into a Brooklyn recording studio to update the groundbreaking vibe that Miles Davis hit three decades ago with Bitches Brew and its successors.

They figured they’d have to reconvene: “Come back. Maybe do some loops; maybe come back again, build some solos.” Make the jams into a real record.

But Tate says he was blown away when he ran back the tapes: layer over layer of siren guitars, woozy bass lines, strings, upside-your-head percussion, spacey piano, vocals scatting into the dreamy funk. It was already there, basically ready to mix and release.

“You know it feels good while it’s happening,” he muses. “But you are barely aware of how much sense it’s making. … Nobody is more astounded than we are when we listen to the record — like wow.”

The record, Burnt Sugar’s self-titled release on Tate’s Trugroid label, is the electric, guitar-driven Miles of the ’70s, as reinterpreted by a generation that grew up on sounds from Parliament-Funkadelic to Led Zeppelin to hip hop and is comfortable with the notion of conducted improvisation. Through hand signals — some borrowed from the pioneering Butch Morris, some developed on his own — Tate guides the development of ideas as they bubble up among the passel of jammers; he poses musical problems, signals what to hold and play with, when to let go.

In the two years since the session, says Tate, the music’s gotten deeper, the group’s gotten bigger (though only 13 members will make the Midwest trek), vocals have become more prominent, and covers (from Michael Jackson to Jimi Hendrix) have entered the churning mix.

Now, with their first Midwest swing this weekend and a three-CD set due out soon, Tate and friends just need an audience to feast on the wild fruit of their groove grove.
