Input: Question: What were the names of the other members of Vells that worked with Green? Passage:In March 2003, Green left the band after suffering a nervous breakdown; official reports stated he was leaving to work with his side project, Vells. The same year, he and Judy appeared on Adam Forkner's first solo album, VVRSSNN. Drummer Benjamin Weikel joined the band, replacing Green, along with Murder City Devils guitarist Dann Gallucci, who had previously played with Modest Mouse. Prior to starting the band’s writing and recording process, Brock was devastated by the loss of "a couple of the most important people in my life," he said. Following these events, the band released their fourth album, Good News for People Who Love Bad News, on April 6, 2004. The following August, the album was certified Platinum, having two hits with "Float On" and "Ocean Breathes Salty" (both of which they performed on Saturday Night Live on November 13, 2004). The album was nominated for a Grammy Award for Best Alternative Music Album that year, and "Float On" was nominated for Best Rock Song. Later that year, Green returned to the band and Weikel returned to drumming exclusively for the Helio Sequence.
