Crowds love summertime concerts because the warm weather keeps them comfortable, and musicians love summertime concerts because it's easier to play a guitar once it's partially melted. Heat up your seasonal agenda with this GrouponLive deal to Bike to the Beach Bash featuring Ra Ra Riot at Montrose Beach. For $12, you get one general-admission ticket for Friday, July 27, at 4 p.m. (a $20 value). The festivities go until 10 p.m.

The inaugural Bike to the Beach Bash beckons revelers to the sandy shores of Montrose Beach for an evening of tunes and suds courtesy of LandShark Lager. After securing their two-wheeled chariots with valets from Blackstone Bicycle Works, attendees can sip libations at The Dock waterfront bar. Crowd members are also free to set up camp on the sand, where they can tie their beach towels together to form a giant slingshot that launches them to the stage.

At 7 p.m., Ra Ra Riot, a baroque-pop quintet from Syracuse, New York, begins its set. The band members lace their sunny power chords with melancholic violin in tunes such as "Can You Tell" and "Dying Is Fine," infusing the summer with more than a hint of introspection. Though they exhibit lilting male vocals that evoke comparisons to Keane and preppy hooks that conjure Vampire Weekend, they flourish in a style all their own, earning them almost 110,000 fans on Facebook and cross-country tours to endless music festivals. Proceeds from Bike to the Beach Bash benefit Intuit: The Center for Intuitive and Outsider Art, a local art center, and Blackstone Bicycle Works, a South Side community bike shop that caters to underserved youth.
