Frontman Wayne Coyne says Lips are working on new songs with former Bad Seed – and other artists – and hope to collate results on April album

The Flaming Lips have revealed they are working on a "collection of songs" with Nick Cave. As the band unveil their newest release – a 24-hour track, embedded in a real human skull – they have confirmed plans to team up with Cave at the end of his current tour.

"We've done a couple of things with Nick," Lips leader Wayne Coyne said in an interview with Pitchfork. "We already have one really good [cut], so that seems like it'll work out." Since January, the Oklahomans have already issued collaborations with Neon Indian, Prefuse 73 and Lightning Bolt, with a four-song Deerhoof EP due in December. According to Coyne, they have also initiated projects with No Age, Stars, Death Cab for Cutie, Lykke Li and Ke$ha. They hope to collect all of these team-ups for an LP in April.

In the meantime, the Flaming Lips are offering the natural follow-up to their six-hour song, released last month. The new track, 7 Skies H3, is 24 hours long. It comes on a hard drive encased within a real human skull. And it goes on sale on 31 October, costing $5,000 (£3,100). "It's a pretty exotic art object," Coyne admitted. "Only 13 of them are being made." To celebrate the new song's release, the Flaming Lips have accepted a 17-year-old girl's invitation to play at her house in West Virginia. "All of her friends are going to come over," Coyne said. "We're going to play Halloween by the Dream Syndicate and then do one or two Flaming Lips songs before the police show up to shut the thing down."

The Lips will also appear at MTV's online O Music awards. After an introduction by Yoko Ono, the band will use iPads to perform the Beatles' song Revolution, a tribute to Apple CEO Steve Jobs, who died on 5 October.
