You might not recognize him from his slim-faced early years in the Black Crowes or his tuxedoed marriage to Kate Hudson, but once he opens his mouth to sing, there’s no mistaking Chris Robinson. Out on the road with a new band, the Crowes vocalist yelps and hollers his way through new and old material with the Chris Robinson Brotherhood on Thursday, April 7, at the Mystic Theater. 21 Petaluma Blvd. N., Petaluma. 9pm. $21. 707.765.2121.
