Not a band I ever was into (my brother was), I'm still surprised you've never even HEARD of the Jam up to now? No "Town called malice?" No "Going underground?" No "Start"? Weird. You must be very young (or in residence under a rock)
not to have heard of them, as they were pretty huge in the late 70s/early 80s, and of course Weller went on to fashion his own solo career with the Style Counsel.
FYI, the Jam weren't thought of as punk at the time of their success, they were known mostly as a "mod" band, and in fact pretty much carried the mod scene.
Good review again; nice to see you expanding your musical horizons (says he, preparing to enter the dark and murky world of boybands --- brrr!)
