Long-running Canadian trio Rush deserves some respect, after keeping it real and technically proficient for 30 years. And since imitation is the sincerest form of flattery, they'll surely read this a cappella version of the classic instrumental track "YYZ" (It's named after the Toronto airport! And there's some Morse Code or something in it!) as a respectful tribute. The group responsible is called Acrapella, so that should give some indication of what they're aiming for. Enjoy, and tip your hat to Buzzfeed.
