There’s a reason that Matt & Kim shows sell out every time they come to D.C.: the duo are extremely happy to be onstage performing and their energy is infectious. The smiles on the faces of keyboardist/singer Matt Johnson and drummer/singer Kim Schifino are wide enough to light up the darkest corners of the 9:30 Club. Despite their constant movement into the audience, onto their equipment and up the scaffolding that held up their light setup, Matt & Kim placed their instruments as close together as the 9:30 Club stage would allow. Their hyperactivity made Sleigh Bells look like slackers and the onstage chemistry was oh-so-cute — except when it wasn’t.
