Steven Sandifer, Whitt Algar, and Dave Grimm anchor this weekly jam session on the Deck Stage at the Pour House, with a rotating cast of guest musicians showing up to keep things unpredictable. It's a loose, collaborative format — less of a polished concert, more of a musicians' hang that the audience gets to be part of.
Monday Mash-UPS runs every Monday evening starting at 6 p.m. and is free to attend, making it an easy low-key option for starting the week with some live music out on James Island.
