Music and the Explosion. "I Don't Wanna Know" was released as a single on February 14. Between early March and late May, the band went on a headlining club tour, dubbed the Back to Basics Tour. They were supported by Reggie and the Full Effect and Eisley. Reception Critical response Entertainment Weekly writer Sean Richardson praised the band for adding tracks that range from "string-laden balladry (”I Don’t Wanna Know”) to surging hardcore (”At Least I’m Known for Something”)" alongside their pop punk repertoire, concluding that "They may have eyes for the Top 40, but these skater boys still know how to rock." Johnny Loftus from AllMusic said, "Catalyst doesn't quite graduate New Found Glory from the punk-pop rungs. From its main aesthetic thrust to the pristine mixing and production, this is a slick and durable Drive-Thru missive, micro-tweaked for maximum Warped Tour ROI. Still, the guys in NFG have been at this a while, so a little exploration is not only understandable, it's expected. To that end, Catalysts East Coast hardcore kickoff is welcome." Rolling Stone writer Kirk Miller gave note of the '80s thrash metal aesthetics that tracks like "This Disaster" and "At Least I Am Known for Something" utilize, as well as other various subgenres ("hardcore punk, synth-rock and emo-tinged ballads") throughout the track listing, concluding that "[T]he band's extra effort shows, giving its pop glory some newfound energy." Robert Christgau graded the album as a "dud", indicating "a bad record whose details rarely merit further thought." Writing for the Chicago Tribune, Blair R. Fischer criticized Jordan Pundik's vocal performance for getting "more irritating with every song." Commercial performance and legacy The album debuted at a career-high number three on the Billboard 200 chart, after selling 146,000 copies in its first week. It was later certified gold by the Recording Industry Association of America (RIAA) in August 2004. As of June 2005, the album has sold over 600,000 copies. The "All Downhill from Here" music video was nominated for Best Breakthrough Video at the 2004 MTV Video Music Awards. Philip Obenschain of Alternative Press said the album was a "nostalgic snapshot of a mid-career transition", which not only displayed what the group were capable of when under pressure, but also that "pop-punk could reach a broader radio and MTV audience without compromising its credibility". In 2016, Gilbert ranked Catalyst as his second-to-least favorite New Found Glory album.
