Two dormant giants of experimental rock, Lightning Bolt and OOIOO, have teamed up for a split LP, The Horizon Spirals / The Horizon Viral. The Thrill Jockey labelmates will release the record on the label on April 24. OOIOO—the longstanding project led by Boredoms drummer YoshimiO—has also announced a rare live date, playing Open Melody Festival in Los Angeles, with more shows to come. Listen to Lightning Bolt’s “Cloud Core” below.

Lightning Bolt drummer-vocalist Brian Chippendale said in a press release, “OOIOO set the tone with The Horizon Spiral but we didn’t really roll with the spiral theme. We’re more Viral than Spiral though they both can dump you in a rabbit hole and we definitely like rabbit holes.”

Lightning Bolt’s last album for Thrill Jockey was 2019’s Sonic Citadel, though the duo has since released some music ad hoc via Chippendale’s Patreon. OOIOO released Nijimusi in 2020.
