BLUESFEST: Beth Hart + Robert Cray Band

The raw, powerful voice of this Californian singer-songwriter brings to mind one Janis Joplin, which is no bad thing. Her performance at this year's Bluesfest will no doubt include material from her 2012 album 'Bang Bang Boom Boom', but we'd be very surprised if she didn't also break out her 1999 hit single 'LA Song (Out Of This Town)'. Also on the bill is renowned US blues guitarist Robert Cray.
