British singer/songwriter/guitarist Robyn Hitchcock may be fully gray-haired now, but his music possesses an evergreen sheen. With his accomplices in the Venus 3—Peter Buck, Scott McCaughey, and Bill Rieflin, plus former Harvey Danger frontman Sean Nelson—Hitchcock should be engineering another smile-intensive night of gently twisted psychedelic pop and between-song stream-of-subconscious ramblings. His catalog bursts with beautifully wistful melodies and smart, weird lyrics, and if we’re lucky, maybe Hitch will toss in a couple of Soft Boys tunes.
