How many hyped-up rock fans can fit into the cozy West 7th cocktail bar White Squirrel? The whole neighborhood is about to find out at the last installment of Big Salt’s March residency. The four-piece throwback crunchy rockers—who also happen to be the next big thing in MSP music—conclude their run (and celebrate drummer Milan’s birthday) with a huge supporting lineup of sludge duo Warcake, power(ful) trio WRRC MPLS, and the recently returned from SXSW buzzband The Bad Man. This show is essentially a summer block party lineup in a corner bar for free, so arrive in time to get in before they hit capacity. FRI, 8 PM. Free.
