An incredible record from Sun Ra! The session was recorded in New York in the late 60s – and it features Ra playing the "solar sound instrument", which is actually a modified Hohner Clavinet, used here with some really spooky sounds! The setting of the album is spare and moody – with Ra striking out first on the "solar sound instrument" – laying down a groove that's filled in by John Gilmore on tenor, plus additional percussion by Robert Barry (who plays a bit of the "lightning drum"), Clifford Jarvis, Marshall Allen, and Pat Patrick.
