2015 album from the blues guitarist. With bristling energy, unflagging virtuosity and lyrics that cut to the core of human hope and willpower, Walter Trout's album, Battle Scars, chronicles his horrific battle with liver failure. But the 12-song set captures the international guitar hero, on a new high - playing and singing at the peak of his abilities, infusing even his darkest numbers with creative joy that sweeps like a beacon. Battle Scars is Trout's 18th album released by the Netherlands-based Provogue label and his 42nd overall, counting his pre-solo-career recordings as a member of the historic groups: Canned Heat and John Mayall's Bluesbreakers.
