All three members of The Slip sat in with Les Claypool and his Frog Brigade last night at Lupo’s in Providence, RI. Drummer Andrew Barr, bassist Marc Friedman and guitarist Brad Barr took the stage for the encore, a cover of The Beatles’ “Tomorrow Never Knows.” Frog Brigade saxophonist Skerik also joined The Slip during their opening set for “Don’t Foil the Mohel.”

On September 15, The Slip will host SLAC Fest (Sustainable Living Awareness Concert) in Coventry, RI. Proceeds from the one-day festival will benefit The Apeiron Foundation. Complete details will be announced later this week.

The band plays Friday at the State Bridge Lodge in Bond, CO. For more dates, visit www.theslip.com.
