If ya never understood what crusty punk was and how it related to grindcore, and where NYC ska worked into this grimy punk thing, check out Leftöver Crack.
Santa Cruz represents! Both bands draw influence from hardcore, punk, and the Deftones. Sometimes jazzing it up, sometimes hanging from the heartstrings.
Guitar riffs fly everywhere, drums speed up and slow down, the whole band stops and starts on a dime, and they even find time to give the bassist some.
Call it peppy pop or punkpop or melodic-laden whoa-whoa punk or whatever, just get it, groove on it, and realize that a lot of bands still have a lot to learn.
