Last night, Hunters & Collectors brought its 2014 tour to Sydney for the first of two club dates at the Enmore Theatre, and treated fans to an encore surprise, inviting Peter Garrett and Jim Moginie of Midnight Oil onstage to help blast through a cover of The Saints’ “Know Your Product.”

By now you’ve heard about R.E.M.’s Mike Mills breaking the news of David Letterman’s retirement yesterday, but here’s the reason he was even there: Mills and former bandmate Peter Buck reunited on “The Late Show” to back Joseph Arthur’s performance of “Walk on the Wild Side.”

Gary Numan’s just about done with this North American tour to promote last year’s Splinter (Songs From a Broken Mind), but he’s still found time to slip out a new music video for the record’s “I Am Dust” — an effects-heavy clip that’s meant to recall the glitchy old days of VHS tapes with tracking problems.

Throwing Muses played a handful of U.S. dates earlier this year, and while the band was in Seattle, Kristin Hersh and Co. stopped by KEXP for an on-air session during which they performed four tracks off last year’s sprawling double album Purgatory/Paradise, and discussed the comeback record.

New Order, which began making noise about recording new music not long into its current reunion, finally treated fans to some of that work this past weekend during the band’s slot at Lollapalooza Chile, debuting a new 6-minute number that bears the working title of “Drop the Guitar,”

The Cure played their first of two shows Friday night at London’s legendary Royal Albert Hall as part of the annual Teenage Cancer Trust concert series, treating fans to a marathon 45-song set that featured some true surprises, including the live debut of Disintegration-era B-side “2 Late.”
