"Shadows" is significant for another reason: it's the first time someone (Theresa, in this case) came to the table with a fully-arranged composition, leaving Warpaint's other members to color outside the lines with such experimental touches as upturned snare drums, floor-bound cymbals, and overdriven water bottles.

I'm drunk and I'm tired,
And the city I walk in, the city I walk in,
It feels like it swallows,
