this is an escalator near the hotel where i stayed in brussels. here’s a video of it. listen to the sound it’s making.
doesn’t the beat remind you of Blood Makes Noise by Suzanne Vega (from 99.9F)? It did me, so much so i’ve downloaded the best of Suzanne Vega to revise some of her songs.
actually, now i listen to the song and the video, the link is quite tenuous, but at the time it worked.
