Bad Brains is the greatest hardcore band of all time. This is not an opinion, it is a fact. The band is the bridge for when the genre stopped being just punk and it became hardcore. Their departure from DC to New York laid down all of the foundations for NYHC. Their ROIR Sessions (which were recorded in NYC) predate the likes of Victim In Pain, etc. Their performances at CBGB are what would pave the way for what was happening later in New York. The Cro-Mags don't happen without Bad Brains. The Beastie Boys don't happen without Bad Brains (put that in perspective). There is no band that is more important to the history of hardcore than the Bad Brains. Included is all of their albums and the live album from CBGB in 1982. This is as essential as it gets.
