A bit of an update on the whereabouts of brotzmann junior.
I found some film of him playing a show in April this year with fm einheit in Porto. Einheit's myspace blog (posted just after the gig) makes reference to Brotzmann taking time out to bring up his baby son.
So perhaps he's starting to get active again now. Hope so.
