Arcadium

This obscure psychedelic band issued one rare album, Breathe Awhile, in 1969 that's very much in the downer-heavy school of the genre. The group's dominant figure was its songwriter and lead singer, 12-string guitarist Miguel Sergides. The ominous, loud, cathedral-like organ; distorted guitar; and anguished vocals took influences from the likes of the Doors, Iron Butterfly, and Vanilla Fudge, while some San Francisco psychedelia could be heard in the bittersweet harmonies.
