Tonight may be a contender for one of the busiest music days in Buffalo in recent memory. Adding to an already bloated 4/18 is a showcase at Nietzche’s. Scheduled to play is pop-punk trio, American Low, Brooklyn’s psych-pop outfit The Midnight Hollow, indie rockers M.A.G.S., and the surfy Bryan Johnson and Family. Doors are at 9pm with a $5 cover.
