Sarasota’s Good Graeff just landed on the national indie rock scene in a big way: In April, the band’s single “I Want That” was featured on the season finale of HBO’s hit comedy-drama Girls.

Good Graeff—twins Brooke and Brit Graeff—started playing music together at Riverview High School. After they won Riverview’s Battle of the Bands in 2004, they decided to keep playing music and set up everywhere from formal competitions to local street corners. After a six-year break, they started to make music again while on a trip to Vietnam. Brooke plays guitar and sings lead vocals, while Brit plays cello and sings backup.

The duo describes their sound as “indie rock/pop,” citing influence from The Pixies and Blink 182. At once dreamy and harsh, they layer vocals over pop melodies, with Brit using the natural tone of her cello to create a bass beat.

When they found out that “I Want That” was going to be featured on Girls, whose music is hand-picked by actress and series creator Lena Dunham, they were cautiously excited. “We didn’t know in what capacity it was going to be used,” Brooke explains. “Often these types of features are barely audible, very short or a combination of the two.” But “I Want That” ended up being a major part of the episode, much to the twins’ joy.

These days, Brit and Brooke call Los Angeles home, although they’re currently on a Southeast tour that included a stop at Bradenton’s Pickin’ Picnic last weekend.
