Red Hot Chili Peppers star Flea has dismissed speculation he has created a new supergroup with former members of now defunct cult rock band The Mars Volta. The bassist was rumoured to have joined Omar Rodriguez-Lopez and Cedric Bixler-Zavala's new project Antemasque after videos showing him playing in their rehearsals emerged online this week (beg07Apr14). However, Flea is adamant he is not a full time member of the group, and simply joined the former At The Drive-In rockers to jam on some of their new tracks. He writes in a post on Twitter.com, "Woke to find out I'm in a new supergroup. Hahahaha. Played on some tracks a few weeks ago with my friends Omar and Cedric for love that all." Flea has previously been part of other supergroups including Damon Albarn's Rocket Juice & the Moon and Atoms For Peace with Thom Yorke. The Mars Volta split last year (13).
