It’s not an ordinary lame prom at the Flywheel. Western Mass punks unite wearing their best alternative formal wear as they jam to local favorites, pose in a photobooth, and stop by a temporary tattoo station. The musical lineup for the evening includes pop punk band Nanny, alternative fuzz pop group Kindling, math metal punk band OroborO, atl-country meets punk group Julie Cira & the Wake, and Brinna Dessert. The Flywheel Arts Collective, 43 Main St., Easthampton. 8 p.m. $5 admission with sliding scale donations.
