Last night, Wet made their incredible late night debut on The Tonight Show Starring Jimmy Fallon as the Brooklyn-based trio stunned with a performance of "Weak." With a simple, stark new set up that included an illuminated display of their name, lead singer Kelly Zutrau stepped out from the stage's shadows with those first few notes of the R&B tinged ballad.

The song is one of the band's recently released singles that will appear on their highly-anticipated debut album, Don't You. The project comes out Jan. 29 on Columbia Records. Watch the performance above and catch Wet as they head out on tour later this week. Read more about their new album in our interview with the band here.
