Notorious for shunning concert performances, Steely Dan's improbable live reunion in the mid-'90s eventually turned into a full-fledged reunion album. Since Steely Dan fans went two decades without even the hope of a new record, the very prospect was a delight, but it was also a little worrying, since a botched comeback would tarnish the band's legacy. Fortunately, Two Against Nature is as seductive and alluring as the best of Steely Dan's later work, with a similar emphasis on classy atmosphere and groove.
