2011 UK breakthrough act James Blake has been performing some limited new live material on his current tour. According to Consequence of Sound, he was throwing several new bits in between tracks during his show at London’s Conway Hall last December 4th. You can check out that bootleg portion of the performance (the new stuff comes between ‘Lindisfarne I’ and ‘II’), as well as a special cover of Joni Mitchell's ‘A Case Of You’ below.
