The two bands will kick off the run April 1 in San Antonio. The 20-city trek will cover the entire month and spill briefly into May before closing with a show in Atlantic City, NJ. Dates are below.

"We're very excited for the upcoming tour with Paramore," Jimmy Eat World's lead singer Jim Adkins said in a press statement. "We got to know them last December while playing festivals together. They put on a great show and we think it's going to be an awesome bill."

"If it all ends tomorrow, we will be happy knowing that we got a tour with the band that gave us a reason to play music," added Paramore's Hayley Williams.

Jimmy Eat World is backing last year's "Chase This Light," its first full-length studio set since 2004's gold-certified "Futures." The new disc, which was produced by alt-rock studio vet Butch Vig (Nirvana, Sonic Youth), debuted at No. 5 on The Billboard 200 album chart following its release last October.

"Riot!," Paramore's sophomore set on the Fueled by Ramen label, debuted at No. 20 on The Billboard 200 last June and recently jumped to No. 15. The album's first single, "Misery Business," is in the Top 10 at modern-rock radio, and the video is making serious waves at MTV. The song and video are streaming at the band's MySpace page.
