Last year’s freaky good Scott Walker record The Drift was his first in over a decade, and it isn’t for the faint of heart. The man’s had quite the career, morphing from your mom’s teenage crush as part of the Walker Brothers into an uncompromising avant artist — and he’s got some fancy fans. The forthcoming documentary, tracing his progression from ’60s pop star to reclusive genius, will premiere in London on 4/27 (with a possible advance peek at SXSW). Looks amazing. Among the interviewees: David Bowie, Jarvis Cocker, Damon Albarn, Brian Eno, Johnny Marr, Sting, Alison Goldfrapp, Richard Hawley, a Cocteau Twin, and some Radioheads. Here’s the film’s trailer, in which you’ll see a flash of Bowie and a flash of Scott punching a slab of frozen meat. That’s what geniuses do.
