Miley Cyrus & Her Dead Petz

Miley, what’s good? ? The lunatic pop princess dropped her surprise new album for free at the end of her hosting gig on this year’s MTV VMAs. And it’s a doozy: a psychedelic concept trip about sex, drugs and her dead blowfish, mostly created in collaboration with the Flaming Lips’ Wayne Coyne. The songs reference this exciting new drug called “pot,” which Miley has discovered and would like to explain to the rest of us. Result: The ex-Disney moppet moans, “How dare you bring another chick in our bed?/You lucky I’m doing my yoga or you might be dead.”

“Something About Space Dude” is the real killer here — an aching acoustic sex ballad about a Bowie boy who isn’t even there, leaving her to sob, “I want to be there skateboarding in a space dude’s evil lair.” Most of Dead Petz sounds pretty much like the Lips’ latter-day output — she aims for Coyne-like high notes that don’t suit her lowdown voice. But she scores wacko successes like “Milky Milky Milk,” “Cyrus Skies” and “Slab of Butter (Scorpion),” along with cameos from Big Sean, Ariel Pink and producer Mike Will Made It. Her best line: “Your lips get me so wet/While I’m singing all the verses from the Tibetan Book of the Dead.” Relax and float downstream, girl.
