Daydream Nation by Sonic Youth (1988)...sonically tight and kinda all over the place at times, it's easily their best rock album. Steve Shelly's drumming (during the good portions) make drum "gods" like Neil Peart envious. Upbeat and innvotive as well as tight. Nirvana owed something to certain riffs from it. My favorites on there are Teenage Riot, Silver Rocket, The Sprawl, Eric's Trip, Total Trash (until it starts meandering for 5 minutes..) Rain King, and Kissability.
