I first bought this album on cassette (I know!) while I was at uni many moons ago. I've since bought it more than once (for myself and friends as gifts) and I would quite happily buy it if my copy ever went missing or got scratched.
For me its they're best album because its the original Green Day raw and at the time totally unknown. Other albums do come close I love American Idiot, and Insomniac (and other albums also have the odd classic track). They reminded me (at long last) of the classic british punk groups of old times which until this album was almost forgotten!
If you've not bought this and you like any Green Day album or even song you'll love this album guaranteed!
