The classic and alternative rock band Krome is making a return to the local stage from 7 to 8:30 p.m., Tuesday, July 21, at Festival Plaza in Auburn as part of the Tuesday night concert series put on by the Auburn Parks and Recreation Department. Though the band was formed about a decade ago, this is actually a reunion concert of sorts, according to bass player Todd Corey. Other band members, who all live in the central Maine area, include Steve Grenier, guitar; Renald Lefebvre, vocals; and Randy Donovan on the drums.
