To me this is where Sonic Youth really start to shine. Their songs got more expansive and yet feel more focused and infectious than before. Perhaps it was the pressure of the higher dollar studio time? I love them most when they give their songs room to breathe with extended instrumental passages. Kinda punk-prog. I'm also a fan of the jam to song method they developed these songs with. Perfect balance of capturing that wild vitality but refining it into something more structured.
