Bob Mould is the latest musician to use Reddit to host an AMA (ask me anything) with his fans, and today's conversation provided quite a few little tidbits—the most timely of which was a preview clip of his new concert DVD, See a Little Light: A Celebration of the Music and Legacy of Bob Mould, which features him performing with Foo Fighter and recent Paul McCartney collaborator Dave Grohl. Mould says he'd love to keep collaborating with Grohl in the future, "As soon as he stops hanging around with that McCartney guy. I keep telling him Sir Paul is nothing but trouble!" From the sounds of things, the two have been cultivating a mutual fandom for years now. 

Other points of interest from the AMA? He says the punk he helped to invent has made a return in recent years with bands like Cloud Nothings and METZ; Zen Arcade is one of his top five favorite albums he's worked on; and he remains diplomatic yet distanced from his Hüsker Dü bandmates. "I don't stay in touch with Grant [Hart] and Greg [Norton] beyond the occasional business correspondence," he told one fan. "Great first band to be in, that's for sure. I wish them both well in whatever they choose to do. No heat, I just moved on." [Reddit]

English midnight-pop group the xx are throwing a yule log on the fire this season with a new take on Wham's holiday classic (?) "Last Christmas," which they have adapted to suit their slow-burning electro aesthetic. The track was recorded at BBC Radio 1's Live Lounge and is available as a free download via the SoundCloud embed below. [SPIN]
