Like a reclusive baron, concerts become more vivacious and less likely to rely on funereal organ music when moved outdoors. Enjoy less dour melodies with today’s Groupon to the Frederick Brown Jr. Amphitheater in Peachtree City. Choose from the following options:

• For $10, you get one reserved-seating ticket to Swingin' Medallions on Saturday, July 2, at 7 p.m. (a $20 value)
• For $25, you get one reserved-seating ticket in level 2 to Kool & The Gang on Saturday, July 16, at 8 p.m. (a $50 value).
• For $25, you get one reserved-seating ticket in level 2 to 10,000 Maniacs and Edwin McCain on Saturday, August 20, at 8 p.m. (a $50 value).

Voted Best Live Music Venue in 2010 by Lifestyles magazine, the Frederick Brown Jr. Amphitheater's sprawling outdoor space hosts musical acts both local and international. Sway shoulders in time to the ebullient melodies of the Swingin' Medallions, whose flashy horn section trumpets its own excellence, issuing notes with the brassy confidence of a currency counterfeiter. Two-time Grammy-getters Kool & The Gang coax even the most timid bodies into fits of rug cutting with funk-infused beats and soulful influences.

Thirsty cochleae can guzzle the structured sounds of alt rockers 10,000 Maniacs or sip the smooth strains of Edwin McCain’s heartfelt songs. Concertgoers can bring their own food and drinks to the performances, but prohibited items include umbrellas, lawn chairs, glass bottles, and lunch pails containing piano-playing frogs.
