It all started with the 88 keys of an old organ. This month's Artist to Watch, Fitz & The Tantrums, is a six-person outfit of soul + pop and some really quite dapper suits. It only took a year for them to hit it big, and they're still growing--there's got to be something good about a band that can coast to sharing stages with Maroon 5 and Sharon Jones and the Dap Kings on just an EP.
