When I first saw the neo-soul act Fitz and the Tantrums at SXSW in 2010, I was struck by three things: the members’ stage presence, their incredibly catchy songs, and how tightly they played as a band. Clearly, I thought, they were destined to be huge.

The band has only become better at those things over the past four years, and is fast becoming a household names. At Fitz and the Tantrums’ sold-out 9:30 Club show on Saturday, lead vocalist Michael “Fitz” Fitzpatrick and co-vocalist Noelle Scaggs very visibly put all of themselves into their performance, which is commendable, especially considering that Fitzpatrick was a little hoarse and not feeling well. “In case you haven’t noticed, we like to get down,” he said during “Moneygrabbers.” He then instructed the members of the crowd to crouch down and “get ready to jump up and lose your fucking minds” during the last chorus (which they did). As of last night, confetti from the show was still falling from the club’s rafters.
