After recording two great albums of dark, moody, clarinet-centric jazz — 2007’s Currents and 2011’s Post Scriptum — the Wolfert Brederode Quartet either called it quits or decided to take an extended vacation or did something because they haven’t made an album since. But fans of that foursome can rejoice, sort of, as a spiritual successor has emerged with Characters On A Wall (CD, LP, digital), the new album by atmospheric clarinetist Louis Sclavis and his similarly-configured quartet.
