Today, Trent Reznor dug a few gems out of his archives, posting high-def videos of four June 23, 2006, radio performances he taped in Boston with Peter Murphy during Nine Inch Nails’ 2006 With Teeth tour.

Dinosaur Jr guitar slinger J Mascis has teamed up with two members of Cobra Verde and one of his Witch bandmates for a new project: Sweet Apple, which delivers its 12-track debut album, Love & Desperation, on April 20, and is expected to tour later this year.

Last year’s six-string doc “It Might Get Loud” was a must-see for fans of U2’s The Edge, Jimmy Page of Led Zeppelin or The White Stripes’ Jack White — or anyone, really, who appreciates loud rock guitar. The film’s out on DVD now, and here’s one of the deleted scenes that appears as bonus on the disc: It’s four minutes’ worth of The Edge soundchecking solo, running through concert staples “Until the End of the World,” “Pride (In the Name of Love”) and “Bad” alone on guitar, with just the aid of his foot-triggered console of effects.

Rock iconoclast Lou Reed next month will issue a digitally remastered edition of his oft-derided 1975 guitar-feedback opus Metal Machine Music on a trio of audiophile formats, and mark the occasion by taking his Metal Machine Trio to Europe for a brief tour billed as “A Night of Deep Noise.”

Is Steve Jobs a big fan of The Cure? Someone at Apple apparently is, since the company used an piano-based cover of the band’s 1985 single “Inbetween Days” — which attentive Slicing Up Eyeballs readers now report is performed by Ben Folds — to soundtrack its eight-minute promo video for the just unveiled iPad tablet computer. Wonder whether Robert Smith will make a pretty penny in royalties off this one?

Florida-based record label 24 Hour Service Station next month will release a two-disc tribute to New Order, proceeds from which will benefit the Salford Foundation Trust’s Tony Wilson Awards, established in memory of the late Factory Records co-founder and Manchester musical icon.

Crowded House this spring will release its second album since reuniting in 2007, an 11-track, as-yet-untitled disc that Neil Finn and Co. will support with a just-announced tour of the United Kingdom in May and June and a slot at the famed Isle of Wight Festival.
