gdlot: @massgiorgini what's the story on the Green Day / Lafayette connection?
massgiorginimassgiorgini: Billie Joe and I co-produced the Riverdales' debut album, which was recorded at Sonic Iguana Studios in Lafayette. Mike Dirnt played bass for the Screeching Weasel "How to Make Enemies and Irritate People" album and did backing vocals for Squirtgun's debut album, which were both Sonic Iguana productions.
