John Bruce Wallace demonstrates his string-torturing techniques again on his latest collection of solo electric-guitar improvisations, Loud Noises in a Corner: Engagements on Urban Terrain. Violent yet lyrical, the five tracks (each identified only by a serial number and the time of day it was recorded) feature squeals, buzzes, squawks, and other Fripperies. Seventy minutes of unedited, non-overdubbed electric attack and decay will be too much for some, and Wallace’s music may not convey the “feel” of the modern world quite the way his liner notes suggest. Still, his playing is a lot less predictable than that of many guitar warriors, and the best of it has a savage beauty that Eddie Van Halen couldn’t achieve with six months of overdubs. The CD is on Wavin’ Bye Records, and available from Wayside Music, P.O. Box 8427, Silver Spring, MD 20907-8427.
