It seems the SoCal alt. stations play the most punk rock - artists such as Pennywise, Face to Face, Bad Religion, Rancid, Social D, etc. Obviously this is commercial punk rock but it's better than nothing. With this style of music being a huge component of what the format is all about, it is amazing there are so many alt. stations across the country that neglect it. Unless I'm missing something but I think I've sampled most of the alt. rockers across the US and it seems that only KROQ, FM 94/9, 91X really give this type of music any significant airplay.
