When brothers Clyde and Billy Hargrove formed their band two years ago, they didn’t expect to reach their level of success so soon.

“We’ve always wanted to play music for a living, but it’s hard,” said Billy Hargrove. “We didn’t know it was going to be so big.”

Clyde and Billy Hargroves are University graduates who majored in mass communication and architecture, respectively. Together with Ryan Robinson, Jason Mills, and Ansley Hughes, they form Super Water Sympathy.

In the two years since the band formed it released its debut album, signed a songwriting contract with Warner Bros., played on Warped Tour and recorded in London. Now the band gears up to play SXSW and looks forward to releasing its second album, “Hydrogen Child” in April.

Tonight, the band will grace the stage of the Varsity Theatre, bringing its unique sound that the members refer to as “water-pop.”

“Every song we’ve ever written coincidentally has some reference to some form of water in it. Whether it be a comparison to a river or even a tear…and we’re very ambient and very ethereal in that sense,” Ansley said.

The band’s eclectic sound results partly from its various influences, which include Sigur Rós, Blink 182, and Blur.

Ansley’s powerful vocals are especially key to their sound — Billy Hargrove described them as being “vicious-elegant.”

“Her voice is awesome…it just cuts through everything,” he said.

Billy Hargrove said the band’s music is a combination of each member’s individual influences. For their yet-to-be-released second album, he said the songwriting method was largely collaborative and influenced by time spent in nature.

“We like to write on the road… next to rivers or water parks,” Billy Hargrove said. We often take a riff from one person and develop it over time.”

Tonight, the band will come full-circle in some ways, playing for the students of the Hargrove’s alma mater. The brothers said their lessons learned at the University still play a part in their success.

“The Manship School [of Mass Communication] enlightened me on many subjects… but it was really the creative writing sessions in the English department where I really learned a lot,” Clyde Hargrove said.

John Donne’s poetry was especially influential for Clyde Hargrove.

“Poetry teaches you how to think and react five steps ahead,” he said. “It’s great mental work for musicians.”

“Every song we’ve ever written coincidentally has some reference to some form of water in it.”
