We’ll never know what music will be like in the future, or on other worlds — but this set offers some inspired guesses. Curated by Keyboard columnist and CreateDigitalMusic.com blogger Peter Kirn, XLR8R magazine, and Pitchfork.com , and inspired by the new SyFy Battlestar spinoff Caprica, it’s a free 13-song MP3 download. Included are tracks by Richard Devine, White Rainbow, Untold, and other computersavvy acts. Lusine’s “Gravity” sets the pace with sliced-up vocals over a mellow beat. Devine’s high-energy sound collage in “Matvec Interior” is both riveting and unnerving. Hudson Mohawke deploys Celtic inflections to spice up a lead synth track in “Fuse,” and the beat evaporates into a thick, dark cloud of echoing sounds in “Toward Water” by Christopher Willits and Ryuichi Sakamoto.

Some of the tracks are drawn from CDs released over the past few years, but Kirn’s “Anaxagoras” is new. It wraps up the set nicely with a rhythmic curtain of high-pitched piano-like tones.
