It’s been six years since the London-based instrumental groove juggernaut Heliocentrics released their terrific debut album, Out There (Stones Throw), a vibrant collage of funk, hip-hop, Sun Ra-inspired free jazz, and cinematic soundscapes. But the band has hardly been idle, putting out ambitious full-length collaborations with the great Ethio-jazz pianist Mulatu Astatke (Inspiration Information 3) and the peculiar American ethnomusicologist Lloyd Miller (Lloyd Miller and the Heliocentrics). The group’s drummer, Malcolm Catto, continues to work in DJ Shadow’s live band, while percussionist Jack Yglesias recently released a debut album by his superb cross-Atlantic collective, Family Atlantica (Soundway), which weaves together sounds from West Africa, the Carribbean, and South America (and includes guests spots by Astatke and the Senegalese singer Nuru Kane; Catto coproduced). On April 30, Heliocentrics return with the heavy 13 Degrees of Reality (Now-Again), a collection of pieces that shows how these various projects and loads of travel have expanded the group’s sound. I’ve only had a chance to listen to the record a few times, but it expertly collides funky grooves and abstract noise, layering found sounds, undulating keyboard tones, fuzzed-out guitars, and clattery percussion over deep, probing rhythms. Today’s 12 O’Clock Track is the epic, aptly titled jammer “Wrecking Ball. Check it out after the jump.
