After decades of litigation, 88 studio recordings made by Jimi Hendrix as a member of Curtis Knight and the Squires between 1965 and 1967 have finally been cleared for release and will soon be available for fans of the legendary guitarist to hear. This isn't all "before he became Jimi" stuff: some of the recordings were made after the release of the Jimi Hendrix Experience's seminal 1967 debut Are You Experienced. While the impending release is exciting news, be warned: Hendrix himself was never a big fan of these recordings. (Rolling Stone)

Lana Del Rey's major labels were skeptical about her new album Ultraviolence, producer Dan Auerbach tells Rolling Stone. A quieter album than her debut Born to Die, and one without an obvious hit single, the release made Interscope and Polydor nervous. No one's nervous any more, though: upon its release last month, the album shot to number one.

Meanwhile, Del Rey was recently in the studio with—wait for it—Brian Wilson. The Beach Boy mastermind is prepping a new album that will also feature contributions from Zooey Deschanel, Kacey Musgraves, and maybe even Frank Ocean. (Rolling Stone)
