I've heard of the acts but I'm not familiar with some of their work e.g. Tom O'Dell - not sure I've heard any of his songs. Will be good to see the Manic Street Preachers.
Lots of well known names to me... not all to my taste but popular. Ed sheeran Emily sande,manics, snow patrol, Gregory porter, camilla cabella, Tom odelll...
I don't know many of the acts but 'Everything must go' is one of my all time favourite albums, doubt I'll watch the full show but I'll keep an eye for the Manics and give a chance for some others.
