Just take those old records off the shelf, because Spencer is about that old time rock and roll.  He's not just about it; he produced a lot of it.  Quiet Riot, Eddie Money, Cheap Trick, and even the Beach Boys were among some of his credits.  Needless to say, he knows his stuff when it comes to the music of the past half a decade.  To learn some of that stuff, watch The Day The Music Died: The Story Of “American Pie" on Paramount+.
