I've never had to complain about noisy neighbours usually because im the noisy neighbour.
One time in adelaide, at a mates place, we started on a few drinks and started playing acoustic guitars... then a drummer would come over... then the big marshall amps would come out... stratocasters... more scotch or rum... its getting towards mid night and my ears are almost bleeding coz we are playing too bloody loud. Then the police rocked up and told us off. half an hour later we were back doing it again.
almost got kick out of blues and roots festival... started up a big band with fellow campers after midnight when the concerts are over. we would have a few guys on guitars, people using wheelie bins for drums, and everyone else would sing.
