U2 have been in New York this past week working on their upcoming album at Electric Lady Studios, which was built opened in Greenwich Village by Jimi Hendrix in 1968. Band members have been spotted there with producer Danger Mouse, reportedly mixing the disc. On Friday afternoon, all four members were on the roof of the studio doing an acoustic version of “Sunday Bloody Sunday” for a camera crew. Also spotted at the studio was Coldplay frontman Chris Martin.

On Friday night, Bono and The Edge played a private show at a party in New York’s SoHo neighborhood.

Chris Blackwell, the founder of Island Records and the man who signed U2, has heard the new album and calls it “better than ever.”

On Monday, Bernie Taupin and T-Bone Burnett will host a listening party for the new Elton John album, The Diving Board, at Electric Lady. That album is due out in September.
