Bad Brains S/T. The self-titled record is nothing shy of amazing. All their stuff is stellar minus the soul brains tours of recent years. Ask Spencer and Garrett Trash Talk about substances that HR does back stage to this day. While you're at it ask them about their trip down Kinsman and up to the Rock and Roll HOF. Then buy their new record...it sounds like this picture of HR I borrowed from :30 under DC: outstanding.
Runners up: Black Flag "Nervous Breakdown," Blood for Blood "Outlaw Anthems," Battery "Until the End," any Bad Religion Record, Blink 182 "Dude Ranch," The Bane 7" with 'Count Me Out' on it, Blue Monday's "Rewritten," Better than a Thousand "Value Driven" and Betrayed's "Addiction" ep.
