Bands have different ways of preparing for shows ... and apparently Jack White likes to do a little back stage jamming to ... Jay Z! 

 

Prior to their first of show at Nashville's famed Ryman Auditorium - which are being streamed live via nugs.tv - Jack was caught on camera jamming along to Jigga

Jack's no stranger to Jay ... back in 2014 he mashed up The Black Album track with his own “Icky Thump”
