I realize Rush is usually a music swear word, but I really do enjoy playing various albums from time to time. In some ways to Pink Floyd, they need to be listened to within the confines of either one album, or in Rush's case a particular period. Rush has so many distinct sounds during (40 years) to make them tough to approach for those not familiar, although really, does anybody struggle in recognizing Geddy Lee's voice? Even those that loathe Rush.
I'd argue they'd be in the final four of easiest Name That Band, bands of all-time.
