Beirut and Metronomy are quite crap headliners IMO (hasn't Beirut's stock decreased considerably since they last headlined in 2011?). Can't say that I've ever listened to Michael Kiwanuka before, but I do like what I'm hearing on Spotify right now.
Very strong undercard as always, and you can't fault them for lack of diversity this time round. There's a lot of great jazz (Moses Boyd Exodus, Nubya Garcia, Nérija), electronic/ambient stuff (Daniel Avery, Yves Tumor), post-punk (Wire, Crack Cloud, Fontaines D.C.), heavy psych (Pigs x7, Kikagaku Moyo) and 'world' music (BCUC, Ata Kak). Probably not quite as good as last year overall, but I'm still super excited for this one.
