In honor of Record Store Day, happening on April 18, indie-rock trio Shark Tape will be selling a random color copy of their full-length release Marathon on the band’s website and at select Philly stores. But tonight's show at Boot & Saddle will be your first opportunity to pick up this rarity. It will also be a good warm up for the group before Shark Tape opens for the iconic house band from The Adventures of Pete & Pete, Polaris, on May 16 at Underground Arts. They'll be joined this evening by Nashville's Future Thieves, who are wrapping up the East Coast portion of their Horizon Line Tour. Boot & Saddle, 1131 S. Broad St., 8pm, $10, 21+ - Bill McThrill
