Los Angeles produced so many classic punk bands and labels that it's tough to label one as the best or the first or so on, so I'll avoid those superlatives when talking about the Weirdos. If they weren't the best, or the first, then at least an argument can be made that they created one of LA's (if not the US) best early punk singles with the "We Got The Neutron Bomb/Solitary Confinement". In fact, the first 2 singless by the Weirdos are essential listening for fans of raw and gritty US Punk.
Unfortunately, the Weirdos weren't able to keep that rough edge for the next two 12" releases . They're not bad ( I prefer Action Design to Who What Where When Why), but once you've heard "Neutron Bomb" and "Solitary Confinement" it's tough to reconcile with the calmer material. Take a listen:
