Portland-based Lefse Records has released Space Project, a compilation of songs that use recordings from the Voyager 1 and 2 space probes. The album, which entered stores on April 19th, features tracks from 14 different artists including Porcelain Raft, The Antlers, Youth Lagoon, Blues Control and British space rock band Spiritualized.

The recordings from the space probes are actually of electromagnetic radiation fluctuations in the magnetosphere of various celestial bodies, according to Lefse Records. The astronomical objects featured in the album are differentiated by their elemental composition, mass and size, thereby producing the unique sounds used in the tracks. All seven pairs of songs, each tied to a different heavenly body, show a remarkable sense of individuality and skill by the artist at mixing the interstellar audio with terrestrial music. Space Project can be streamed from NPR Music.
