Sure, Steely Dan are a decade or two late in delivering Two Against Nature, their follow-up to 1980's Gaucho. But time may finally be on the side of rock's most illustrious music geeks. The old knock on Steely Dan was that they were too good for their own good — if Walter Becker and Donald Fagen had recorded a studio album during rock's extended Amateur Hour of the early Nineties, they might have been publicly flogged. Unlike their El Lay-based muso contemporaries, Steely Dan managed to mix their craft with some truly crazy shit — slick-sounding songs about perverts, assassins, divorcees and other non-strangers. We should have expected no less from a band named after a dildo, albeit a hugely literary one.
