What is the difference between David Bowie's Low and Neil Young's Rust Never Sleeps?

in Low, the first half sounded New Wave-ey and the second sounded New Age-ey. while Rust sounded New Age folk (Ride the Llamma sounded like Enya) on the first side and the second sounded metal(Welfare Mothers sounded like Queen), New Wave, Punk(tribute to Pistols).
