Supersense Festival in Melbourne has announced a pretty amazing lineup over 3 days:
Nazoranai (Haino/O'Malley/Ambarchi)
Spiritualized
The Ecstatic Music of Alice Coltrane
Acid Mothers Temple
Blonde Redhead
Master Musicians of Jajouka
JG Thirwell
They're also bringing back Overground for it which was pretty epic back in 2011 when it was launched at Jazz Fest.
It's essentially all the performers from the festival collaborating in various improv collectives.
The last one featured Tatsuya Yoshida, Faust, Tim Berne, Ches Smith, Mary Halvorson, Charlemagne Palestine, Tony Conrad, Fabulous Diamonds, The Necks, and many others I can't remember.
It seems like Melbourne festivals blew their wad in those first few years I lived down here and the lineups since have been weak.
