Their style transcends just their sound. At their pre-Grammy performance for AMP Radio and Radio.com at the Grammy Museum, the Best New Grammy-nominated group donned their quintessential retro-rags.

Cellist Neyla Pekarek wore toile tights, cocoa brown oxfords and a vintage-looking locket around her neck. Multifaceted frontman, Wesley Schulz, wore a fedora and a charming rough-and-rugged aura that melted the tension from them coming on an hour late.

The culprit of their tardiness was a broken cello. Schulz called out United Airlines for breaking their cello and thanked the band's crew and staff for getting a cello to them so quickly before the band played a five-song set of favorites like "Flowers In Your Hair," "Ho Hey," "Classy Girl," "Stubborn Love," and "Flapper Girl," which was an audience request.
