If you’re in the Philly area, it might be a good idea to block off Saturday, May 6th on your calendar. The Electric Factory in Philadelphia just announced a truly absurd bill to kick off their seasonal outdoor concerts – Mastodon, Opeth, Gojira, Devin Townsend Project, Eagles of Death Metal, and Russian Circles, all on the same stage! EODM are the only ones that stand out as a little unusual in the mix, but a little variety never hurt anyone. This was originally a Gojira/Opeth bill that’s expanded to what’s basically one of the coolest summer fests you could ask for. There’s not much else to say.
