Fiona Apple: “Dull Tool”
Apple’s contribution to the soundtrack to Judd Apatow’s upcoming “This Is 40” could be (and is, maybe?) an “Idler Wheel” outtake: It’s weirdly syncopated, cheerily off-putting, and equal parts awkward and great.

Carnage featuring Katie Got Bandz: “Kat!e”
The L.A.-by-way-of-Frederick producer pays raucous tribute to the Chicago drill mistress.

William Basinski: “Dlp 1.1 Live at The 54th Venice Biennale, October 18, 2008”
The ambient composer’s landmark post-Sept. 11 work “The Disintegration Loops,” made using crumbling, reclaimed tape snippets, was recently reissued in a five-disc box set with additional material like this live track, arranged by Antony and the Johnsons’ Maxim Moston.

Various Artists: “DMV: The Dream Team, Vol. 1”
Fat Trel, Muggsy Malone and a lot of fine MCs you’ve never heard of populate this DMV state-of-the-union mixtape, collated by local rapper-producer General Kamau.

Alt-J: “Slow Dre” (Minogue/Dre mashup)
