At its annual Battle of the Bands competition Saturday, Congress of the South 40 revealed band Timeflies as the headliner for the April 7 WUStock concert.

American pop duo Timeflies features vocalist Cal Shapiro and drummer Rob Resnick. The pair started their music career by performing covers on YouTube and began to amass a fan base with their “Timeflies Tuesdays,” during which they would showcase new music.

They are best known for their album “After Hours,” which debuted at No. 8 on the Billboard Top 200, and their song “All the Way,” which peaked at No. 2 on Billboard’s Top Digital Songs chart.

In past years, CS40 hosted singer Daya and bands BORNS, MKTO and Walk the Moon as WUStock headliners.

Junior Annie Lee is excited for the upcoming concert, although she said she isn’t that familiar with the band’s discography.

“I’ve only listened to their top songs, but I love their summer-y voice, which will be great since WUStock is during the spring,” Lee said.

Meanwhile, freshman Noah Ginsberg is less enthused about CS40’s choice of performer, saying that the band lacks relevance.

“If it were 2013, maybe I’d be more excited,” Ginsberg said. “They’re so irrelevant now.”

As with past years, the winner and top two runner-ups of the Battle of the Bands competition will open WUStock. The Snapchettes came in first, followed by Sami Pathak and the Good Samaritans, with Devin and the Atmospheres taking third place.

Sophomore Dylan Kiefer, drummer for the Snapchettes, is excited for the opportunity to open for WUStock.

“What I really wanted out of this project was to have a good time and play good music with good friends,” Kiefer said. “Being able to do that in the context of WUStock will be really cool.”
