Here's a documentary on the garage rock revivalists of the past several years featuring mostly US bands including the late Jay Reatard, Thee Oh Sees, Davila 666, The Black Lips, and Ty Segall. But also (rightfully) featuring the influence of New Zealand's own The Clean! In Jay Reatard's words (interviewed in the film) garage is "usually three minutes or less, as few words as possible, to convey as much emotion as you can with as little as possible." And here's a link to Pitchfork's Shake Appeal column dedicated to "garage and garage-adjacent releases." For the real old school stuff you can check out a YouTube playlist drawing from the tracks on Lenny Kaye's seminal Nuggets compilation LP of sixties garage punk and psychedelia.
