Brooklyn rockers Blue & Gold deliver an impressive first single in advance of their debut album with the heavy mid tempo “In My Head.” Combining driving guitars with soulful, bluesy vocals, their sound has the instant appeal of an updated version of blues rock. Solid thunderclap drums and a precise distorted bass lock the track down while well-placed power chords and rippin’ lead guitar solos point to the era when Leslie West’s band Mountain triggered the evolution of the electrified blues-rock hybrid. On the second chorus, girl/boy tandem vocals give way to alternating single lines: “Ain’t got no time” becomes the throw-down vocal hook statement, when “I want you” is followed by “why don’t you want me too?” The band will celebrate the release of their album at Mercury Lounge on January 10. - Dave Cromwell
