Definition Time!
I consider myself a fan of the punk rock, but I have a very biased favor for "california" punk - The very distinct SoCal and NorCal sound that developed in the mid 90's, and for, of course, the early Midwest/east coast hardcore stuff (I do not limit myself to these "genres" anymore, of course, this is 10 years ago Im talking about.)
As a kid I generally dispised English punk (especially the clash and the sex pistols. What can I say, I still think the Sex Pistols were terrible. I have learned the error of my ways in regards to The Clash though), and, what I assume, most 0i music as well.
But what is Oi? I have my idea's about the general sound is - Crass, Cock Sparer, The Buisness, Fear (?) - but is the genre defined by it's general sound (which is really just low-fi, low talent punk), or are the Implied/Assumed politics of the band a requirement as well. What am I missing here? What makes Cock Sparrer Oi but, say, Rancid not Oi?
