This is where any aspiring fan of hardcore punk should start. This record (as the title suggests) is all the material released by Black Flag 1977-1981. It's not quite the same as the Rollins-era band but any fan of Rollins will also love this. The first four tracks (the "Nervous Breakdown" EP) are definatley the best tracks here, all of which have been covered numerous times and become anthems. The "Jealous Again" EP is almost as good and is just as essential listening. Next is the "Six Pack" single. This is different to the version on the "Damaged" LP but in my opinion is just as good (I don't know which I prefer). The "Louie Louie" single is also great and the album ends with it's b-side "Damaged 1" which again is different to the "Damaged" album version. Forget the low-fi production or the occasional bum-note and missed beat, this is what punk's all about. Totally essential raw brutal punk at it's finest.
