Another hot guitarist with a rockier edge is Walter Trout. A former member of John Mayall's Bluesbreakers, Trout has amassed a huge following in Germany. With his self-titled debut (Ruf Records 51416 1349 2; 74:00), recorded in Memphis and produced by Jim Gaines (ZZ Top, Johnny Winter), Trout hopes to break through the U.S. market. His flashy fretboard facility is bound to register with fans of Stevie Ray Vaughan, Gary Moore or rock-blues upstarts like Kenny Wayne Shephard and Johnny Lang. Fans of real deal blues will not be nearly as impressed by the flurry of notes and rock production values here.
