Mutter Slater Band, “Field of Stone” (Angel Air)-This veteran performer is best remembered these days for his quirky exploits with prog rockers Stackridge almost half a century ago, but Mutter Slater has been blessed with one of the finest voices in British rock and he now has an opportunity to indulge his genuine passion for r&b , blues and soul via splendid albums such as this. The latest addition to Mutter’s impressive back catalogue mines a rich vein of polished melodicism, and devotees of his work in the past would be well advised to lend an ear to heartfelt creations such as “Love is the Stranger,” “Weird Kid” and “Field of Stone” itself.
