Tonight’s mystery artist translated the name of their album into Morse code and incorporated it into part of a song for the album which was nominated for a Grammy. Any guess who they are or the song or album?? 

The album is named after an identification code for the Toronto Pearson International Airport ‘YYZ’. Slightly outside the norm for the band  RUSH this album was an instrumental.  According to Ultimate Classic Rock, the song of the same name's intro riff is based on the visual pattern for those three letters, rendered into Morse code. UCR calls it:

"The most lovably nerdy moment from prog’s nerdiest band."

Here is tonight's featured song.
