san fransisco's the parmesans are hard to classify. part folk revival/old time string band, some doo-wop/50's R&B influence, part barbershop trio? whats for sure is the parmesans can play and sing, specifically in ultra tight three part harmony. their latest album, 'wolf eggs', showcases these strengths well due to the fact it is a live album, which is often the best mode for capturing string bands with strong harmonies.
i think the sort of r. crumb/'comix' style album art fits the sound of the parmesans well. name your price for this and a handful of other album over at their bandcamp.
