Seeing as it was their first proper release, I think it was a bold statement to the state of music that was coming out at that time. I never felt Television was a “punk” band as we think of it, but they fit into that New York scene perfectly because of their artistic and literary style to their music. The song is a journey and sometimes it takes 10 minutes.
It earns every second. Marquee Moon plays like the missing link between punk & prog and the guitar solo actually goes somewhere. It has a beginning, middle & end.
