This was Green Day's first album, and, arguably, the best. It is certainly the rawest, recorded when Green Day were still on an indie label, and the guys were still in their teens. That's what makes this album so special.
It is an album that is very relateable, with songs like At The Library describing Billie seeing a girl, wanting her, then she walks away with her boyfriend, or Only Of You, where Billie wants to pour his heart out to a girl but can't. In fact, most of the songs on here aren't true punk, they're mainly about love, except ones like Road to Acceptance, which is about people following trends etc.
The guitar in this album is pretty special, unlike modern Green Day songs every other song features a fantastic solo of Led Zeppelin standard, stick-out ones include The Judges Daughter and Only Of You. One of the bad points about modern Green Day stuff is the lack of solo's, the only noteable one of their current stuff being Maria.
For an album that was created by a bunch of 3 people still not out of their teens, this is a remarkable achievment, and has a special element that no other Green Day album has. My personal favourites are At The Library, Why Do You Want Him, Only Of You and Going To Pasalaqua.
This album is not for casual Green Day fans who wouldn't know the words to 2000 Light Years away, this is for more serious fans. It is a great album, and certainly worthy of your money. At 60 minutes, it is also a pretty long album.
