*In process of stocking* Produced by Jimmy Curtiss, who is best remembered as lead singer of the great psychedelic folk rock band the Hobbits, Century Expanded’s “Concerto For Wah Wah” was released in 1971 but staged very little impact at the time. Finding original copies of the disc is a real chore, so how cool it is the Gear Fab label will soon reissue this super rare album, which features all instrumentals duly drenched in wah wah guitar action.

The opening track of “Concerto Wah Wah” measures in at over forty minutes in length and initially took up the whole first side of the record. Titled “Melodic Variations In D Minor,” the jam happy work out steers the listener through a mind-messing maze of shifting patterns and trippy and phased effects. Quite a demonstration it is, as are the remaining two cuts, “Rhythmic Variations In D Major” and “Prelude,” which shimmer, sizzle, shake, screech, squeal and soar with inspired noodling and progressive arrangements. Wobbly notes and chords spill and scatter across the loopy landscape, as well as spurts of scratchy feedback and funky blues riffing. Birthed solely for the studio, Century Expanded was one of dozens exploitation acts of the era, but don’t hold that against them, as “Concerto For Wah Wah” is a sheer delight and an invitation to indulge in some serious air guitar playing.
