Like the epic blues LP, Fathers & Sons, which combined young and old, here we find three generations of rock guitarists – Jimmy Page, U2’s The Edge and Jack White – swapping tales, gigging and generally celebrating the electric guitar. Too many moments make this a must-see if you’re a fan of any or all of the performers: historical footage of Page in the early 1960s, The Edge recounting how he and his brother made an electric guitar from scratch, even winding the coils. And to see Page declining to harmonise in a rendition of ‘The Weight’ on the grounds that he ‘can’t sing’ (!) – this is one of the most captivating rock docs in years.
