AJJ is among my favourites! Some I would recommend looking into:
Pat the Bunny and his related acts -> Ramshackle Glory, WIngnut Dishwashers Union, Johnny Hobo and the Freight Trains
Mischief Brew (absolute must - my most beloved song of all time is their Coffee God and Cigarettes) + related act The Orphans (especially For an Old Kentucky Anarchist)
Defiance Ohio - Calling Old Friends
HELL YEAH, have had this song on my mind for the past while... In fact, it is the inspiration for my lemmy username!
