A group of rock heavyweights are getting together to create a star-studded side project.

Pearl Jam's Mike McCready tells the still-untitled band also features former Guns N' Roses bassist Duff McKagan and ex-Screaming Trees drummer Barrett Martin. 

The guitarist says the trio met up and wrote some new material, and adds that they've also been working on some of the unreleased demos from McCready and Martin's other band, Mad Season. 

Mike says they're trying to find some singers to work on the new music as well.  And while there's no specific release plan for any of the material, McCready would like to put it out on his new label. 

He says it would be great to eventually release some of the new songs on vinyl 45s via his Hockeytalkter Records, which takes its name from his three-year-old son's pronunciation of the word "helicopter."
