This Saturday, legendary horror-punk band The Misfits will perform at the Arena Bar and Grill on Martin Street, with doors opening at 7 p.m. and the concert starting at eight. The band was originally scheduled to play at Mezzanine, but the venue was changed and now the show is 21 and over only. Anyone under 21 who purchased tickets needs to see Mezzanine for a refund, according to the Arena's website.
