These obnoxiously large song titles took over Toronto's Billy Bishop Airport last June. They were designed adjacent to the Rock Matters campaign for the Toronto rock radio station, Q107. Aimed at locals, these huge murals intended to pull at some nostalgic strings by prompting travellers to fill in the blanks to famous rock songs. It's pretty easy to figure out once you get the first one. The word missing is "Rock."
Without the word, you don't have the song, visually reinforcing that Rock Matters.
