Godsmack is almost finished recording an EP of cover songs. On Saturday, singer Sully Erna informed fans via Twitter that the band has been in the studio working on it for the last three weeks. "Today is last day of mixing the covers ep we're working on for you. I think you're gonna love this!" Erna wrote. "I want to suggest to management when they're all ready to hear, we throw them up online and let all of you decide which one is best 4 radio."

Blink-182 co-frontman Tom DeLonge is currently touring with his other band, Angels And Airwaves, and he's busy with several film projects as well. Speaking to NME about the rumors that he is currently working on an animated film called Poet Anderson, DeLonge explained, "We've got three movies ideas that we're working on, two specifically; one has a completely written script, which I can't go into yet. But the Poet movie is a very large, ambitious idea; it's about dreams and near death experiences. It'll have the pacing of a mainstream film, but it'll look very artistic. It'll allow us to create a score album that's very different to anything Angels And Airwaves has done in the past." The guitarist also said that the band will be touring more extensively in the next few months and into the summer. Asked how he planned to schedule both Blink-182 and Angels And Airwaves shows during the summer, DeLonge replied: "The Blink tour is in June and then the Angels dates will get worked in after that. But I'll be doing both bands throughout the year. We've confirmed all our production design for the European run. Mark is in London and having an amazing time, he's been writing music. We'll be going strong through May and June."
