I stumbled on a new podcast, Producing the Beatles by Jason Kruppa. They’re short (20 minutes to half an hour) episodes focused on the techniques of the various effects etc that the Beatles used on their records. The first episode dealt with the sped up piano on In My Life. It explored the motivations for using it, had a pianist play the half speed version for comparison and looked at earlier examples used by other artists like Les Paul.
It’s probably more for the music geeks who love exploring the ins and outs of Beatle recordings. But I think most fans would get something out of it.
