Johnny Simmons - Drumset, Percuss., Vocals. Ryan Birsinger - Chapman Stick, Vocals. Atomic Opera is firmly rooted in a rock and metal tradition that began with Black Sabbath and was continued by Metallica, but adds lilting, irresistably Beatles-ish melodies and unexpected, towering harmonies evocative of prog rock bands like Rush and Yes. Add the presence of Frank Hart's sophisticated arrangements for cello, acoustic guitar, mandolin, dulcimer, organ, recorders and hand percussion, and you get a stellar old world art rock sound with a progressive folk metal edge. This brooding yet accessible music was born of same fertile Houston scene that produced Galactic Cowboys, The Awful Truth, and King's X, which shares some of the Atomic Opera's spiritual focus and prog rock influences. 2) Ryan Dalton--vocals Mike Furney--drums Mike Martinez--bass Todd Grubbs--guitar Hal Dunn--guitar 3) Scott Andreas - Vocals Mike Curry - Guitar Doran Lindset - Bass James Root - Guitar Danny Spain - Drums Band released one Demo called "The Judgment" in 1992.
