Music you watch instead of hear, for when the song alone can't justify the ticket price.

means A synchronized display of lights, lasers, or projections used to add visual spectacle to music, a building, or a performance.

from A straightforward compound of 'light' and 'show,' gaining its modern sense in the 1960s when psychedelic rock concerts began pairing music with projected oil-and-color displays and colored lighting rigs — a way to make the eyes trip along with the ears. The term simply widened from there to cover laser displays, drone shows, and the illuminated building facades of today.
