Robert Walter juggles multiple projects as deftly as he fingers the keys on his B3 Hammond organ, hands flying across the ivories and executing soulful, funky ass grooves that require you to bring your A-game on the dance floor. Or at least try to execute a few moves.

A founding member of the Greyboy Allstars—his airy SoCal jazz-funk outfit with sax player/flutist/singer Karl Denson—and lively player in Mike Gordon of Phish’s solo band, among various other projects, Walter also leads his 20th Congress. They are currently on the road behind the exploratory, improvisation-laden Spacesuit, which he’s said was inspired by “early fusion, krautrock, dub reggae, the films of Alejandro Jodorowsky and Stanley Kubrick, and the images of Chris Foss, Moebius, and H.R. Giger.” The grooves are deeper, sometimes darker, and more cosmic than usual. I dig it.

Walter and his compadres play tonight at Nectar. Warm-up from McTuff.
