Not sure who's all performing, but the last sentence is worth highlighting:
"In addition to the art on display, the London Launch event will feature appearances from Sonic Boom, Gruff Rhys and Dan Treacy. Will Carruthers, Jonny Mattock, Mark Refoy, Roscoe, Kevin Shields, Pat Fish, Bassman and Natty himself (health permitting) will also be in attendance."
