Celebrate warmer temperatures this weekend by taking in all the glory that summer-to-fall’s lovely transition brings. Our list this week is packed full of free outdoor concerts and some raverific parties. Sneak peek: Garden Potlucks, BBQ Concerts, a oh-so-rare Rubulad party (*update: said Rubulad party has been cancelled*), an electronic music festival from Bang!On, and all around awesome rock’n’roll offerings!
