15. Steely Dan
The 1970s were a trip and Steely Dan prove it: What other era would honor two kinda stoned, laid-back jazz dudes with dad sweaters writing long, literary jams about divorce and getting high and drunk and the Eagles? Aja's the one, their 1977 album with classic Donald Fagen-Walter Becker numbers like "Black Cow" that showcased their cool-guy harmonies and jazz guitar, setting the stage for yacht rock for decades to come. But they had countless stoney guitar jams over a decade, both influenced and hindered by their tumultuous relationship and Becker's drug addiction, leading to their first breakup in 1981. Like the Seventies, though, they just needed time to nurse the hangover, and by the 1990s the boys were back in town. They're still touring and dropping albums, ponytails and all.
