Garth Brooks seems to have set the feathers flying by pitching up in Austin during the SXSW festival. Saving Country Music had a rant about it: http://www.savingcountrymusic.com/go-ho ... g-at-sxsw/ and famous old venue Threadgills has upset locals by cancelling a gig by Johnny Bush so as to accommodate the pre-dinner crowd for a nearby Brooks concert (see below).
He also turned up at The Broken Spoke during a Billy Mata gig and performed a 30 minute acoustic set. This seems to have delighted/upset those in attendance in equal measure! I'm sure there'll be lots of youtube clips of this floating around soon.
