Julian Casablancas has lashed out against his record label, blaming them for the "horribly executed" release of his debut solo album. While a fourth Strokes album is "coming", he insists, Casablancas has been busying himself with the "bullshit" of promoting and distributing Phrazes for the Young.

"Working on music is the funnest thing for me," Casablancas told New York Magazine. "I could do it all day, all night. But there's all this other crap that I just constantly have to do." While the solo record was a co-release by Casablancas's own imprint and major label RCA, "[RCA] are not the label I signed with," the singer complained. "The people change all the time. They're nice, they're cool, but honestly they don't do shit ... I still like the plan, but it was executed terribly."

"You have all these dreams," Casablancas complained. Take his four live dates in Los Angeles last year, a big-budget show with elaborate sets and costume changes – and mostly self-financed. "It was a constant struggle with the venue, managers, lighting guys, video people," he said. "I went broke doing it ... In the end, it wasn't a positive experience for me at all."

Things were just as frustrating with the Strokes. "We split the money ... but we didn't split the work. It was really, really hard." Only recently has the band reinvented its process and begun "working as a group", Casablancas said. "That's only happening now. Literally now ... I think we're fulfilling the promise of what we said we were: actually being a unit that really works on everything."

Phrazes for the Young is out now.
