You don’t have to be a student to enjoy tonight’s “Back to School Extravaganza” at The Granada, 1020 Mass. The Lawrence-based indie group Quite Corral headlines and will be joined by Hidden Pictures and The Low End. Tickets are $5 to this all ages show that runs from 9 p.m. to 1 a.m. Quiet Corral recently released its debut EP on iTunes. Hidden Pictures, an indie-pop band founded in Kansas City’s record bar, is looking forward to releasing its debut album this year. Manhattan’s The Low End also has an EP under its belt. Dabbling in rock, americana and folk, The Low End has been recording its next release while touring the Midwest.
