In the second installment of their Orion Festival, Metallica have yet again booked an eclectic assortment of bands. It's not just a metal festival as one might expect. Aside from Metallica, Red Hot Chili Peppers have been booked as co-headliners. Other acts appearing on the bill include acts as diverse as the DJ Bassnectar, Dropkick Murphys, and indie rockers Japandroids. Said Metallica drummer Lars Ulrich to Rolling Stone: "Our idea was to bring North America the kind of festival experience you get in Europe, which is all about diversity and new experiences."

As it turns out, the members of Metallica have quite broad tastes in music according to Ulrich: "We just made endless lists of our favorite bands; we even reached out to Iggy [and The Stooges] – which would've especially highlighted the Detroit element – but he's got a gig in L.A. that day. If you saw our iPods, you'd see we live that kind of diversity in our day-to-day lives. We love heavy music, but we're music fans above all." This year's Orion Festival will be held on June 8 and 9 at Detroit's Belle Isle.
