Ten years ago, as Sonic Boom’s new sleevenotes attest, he and Jason Pierce were “making hypno-monotony” and smoking a lot of grass. Spacemen 3 were a cult on the brink of brimming over, which soon happened with the spin-off of Pierce’s Spiritualized. Their penultimate LP as a pairing was The Perfect Prescription, here stretched to a double with the addition of various demos and unreleased sessions. In two modes, hippie-trance riffery and hushed faux-religious reverence, it’s love-it-or-hate it puritan-rock. The drugs, clearly, worked for them.
