Watch Banks Light Up 'Letterman' With 'Beggin for Thread'

"Lovely! Wonderful! Beautiful," the late night host exclaimed after the 'Goddess' singer's mesmerizing performance

"Tomorrow night. Letterman. It's mine," Banks tweeted April 2nd, hinting that The Late Show would see an epic performance Friday night. The Los Angeles-based R&B singer delivered on her promise, bringing her eye-catching "Octagon" stage setup to the Ed Sullivan Theatre's stage. On the Late Show, Banks performed "Begging for Thread," the hit single off her debut LP Goddess, one of Rolling Stone's 20 Best R&B Albums of 2014.

"Lovely! Wonderful! Beautiful," Letterman exclaimed after the performance. After the late night host managed to free the singer from her house of mirrors, Letterman himself stepped into the reflective booth to close out the show. "This thing is kaleidoscopic," Letterman marveled, closing the Octagon's door with him and Banks inside.

The Letterman performance marks Banks' third late night appearances since the arrival of Goddess: She made her late night debut in August 2014 with a stop on Jimmy Kimmel Live, which she followed up a month later by bringing her Shlohmo-produced "Brain" to Late Night With Seth Meyers.

Starting in April, Jillian Banks will embark on a summer's worth of music festival appearances, including slots at Toronto's Bestival, Montreal's Osheaga and an August 1st set at Chicago's Lollapalooza.
