Mick Jagger proposed the idea for what eventually became this series to Martin Scorsese back in the mid-'90s.
Was initially renewed for a second season after the pilot premiered. However, HBO reversed the decision two months after the finale aired.
Martin Scorsese said that he and Mick Jagger tried at first to develop the material for what eventually became a television series into a full-length feature film.
Bobby Cannavale was offered the role of Richie Finnestra back in 2012 while doing a season-arc for Boardwalk Empire (2010), so he had years to prepare it.
The fictional recording label American Century Records portrayed in the series is abbreviated as ACR, which is the reverse of RCA, which is a real music label owned by Sony Music.
Once it was decided to be developed as a TV show, Terence Winter wrote the pilot but his idea was to hand over the show to George Mastras because he was busy with Boardwalk Empire (2010). The show took so long to be made that Winter ended up running it because "Boardwalk Empire" finished on its own.
Ray Romano landed the part of Zak because Martin Scorsese liked his audition tape, even though Scorsese had never heard of Romano before then or knew much about his hit TV show Everybody Loves Raymond (1996).
The song "All the Way From Memphis" by Mott the Hoople was also heard in Martin Scorsese's Alice Doesn't Live Here Anymore (1974)..
