You'll have to forgive them, but the origin story of Fitz and the Tantrums as dictated by eponymous frontman Michael Fitzpatrick is not an especially original one. "Basically, [the project] started with me heartbroken," he says, "losing my friggin' mind." (A scenario that plenty of people are forced to solve without the Billboard charts.)Thankfully, that generic starting point isn't reflected in the band's music, which pastiches influences from doo-wop to jazz to pop into a deeply soulful and emotionally resonant amalgam. Songs like "Don't Gotta Work it Out" and "Out of My League" twinkle and soar with romantic yearning that moves along at a comfortable, breezy pace, the band sounding like the kind of nightclub house act that can dazzle on any random night. How do they manage to sound so laissez-faire? It's born from a genuinely appreciative take on the band's success thus far, which isn't always easy to find in a reflexively cynical music industry. "I always say it's 23 hours of grind for that one hour of glory," he says. "I get to go out every night and do this complete experience, and the more we give, the more they go crazy. It becomes this energy loop. Like, I just wrote those songs in my living room late at night and I wasn't expecting it to have that kind of effect."Sure, that sounds a little New Age-y (First come energy loops, then healing crystals, then chakra alignment, then a booked trip to Burning Man), but according to Fitzpatrick, it's a perspective that's already been validated from their current travels. "We had gone out on the road," he says. "We had just played our local NPR station in LA. We came back and played this little nightclub and when we got on stage, everybody was singing back the words with us so loud. We all in the band collectively took a step back and went, 'Whoa.' That's already making it to me." Pretty simple, right? When you take pleasure in such small moments, anything bigger must feel like the greatest thing in the world. They'll have plenty of experience with that soon enough.
