Chris Robinson sat in with The North Mississippi Allstars last night at Hollywood, CA’s The Roxy. Robinson—who plays with NMA guitarist Luther Dickinson in the Black Crowes—sat in on “Poor Elijah / Tribute to Johnson.” The Black Crowes regularly perform the song live. The Chris Robinson Brotherhood will appear at Los Angeles, CA’s Echoplex on March 28. The members of the Black Crowes will regroup for a short European tour this summer before beginning an indefinite hiatus.
