Roger Waters sat in with Lucius at New York’s Beacon Theatre this evening. The Pink Floyd confounder emerged during the group’s encore to sing and play acoustic guitar with the band on a version of “Mother,” from 1979’s The Wall. 

Lucius singers Jess Wolfe and Holly Laessig first crossed paths with Waters in 2015 when they backed him at Newport, RI’s Newport Folk Festival as part of an all-star combo that also included My Morning Jacket and GE Smith. The singers went on to tour with Waters for a few years as part of his solo act. 

Waters’ cameo was part of a highly collaborative week for the members of Lucius. Last night, both Celisse, members of Stay Human and Sheryl Crow–who lent the band’s core songwriting duo her home to work on their new Mom & Pop album, Second Nature–joined Lucius on The Late Show. Celisse also opened the ensemble’s Beacon show and emerged during Lucius’ set for “Dance Around It;” Trey Anastasio, who employed her for both his Ghosts of the Forest project and Phish’s 2016 Halloween tribute to David Bowie, attended the show and watched and shared photos from the side of the stage. 

Lucius will perform at Montclair, NJ’s Wellmont on Friday.
