Ostensibly a documentary about a classic drum machine - the Roland TR-808 Rhythm Composer - it's disappointing how little detail there is in this film about how it's actually used, as opposed to how widely it's used. It features an impressive array of interview subjects, all musicians and producers who love the 808 and have created huge club tracks with it (while Phil Collins and his "Another Day in Paradise" are brushed over quickly), but I don't think most people think of the percussion lines on those records primarily, and the documentary gives you little reason to change the way you listen to them.
Some talking heads are more interesting than others, of course, and my interest in music production…
