The first ever release of a heavy, acid-rock influenced power trio that was active in Denver, CO during 1971-'72. This album of archival material consist of recordings that were produced by bouncing tracks back and forth between two-track and four-track reel-to-reel tape recorders. And these guys didn't forget to add some weird and spacey effects along the way either. This CD-edition comes with a 16-page booklet, offering lyrics, photos, plus interesting and funny details about Umbra's history.
