Hi RedFive! When you say you have the 'complete discography' does that include the 'mono' albums? If not, I would absolutely recommend the mono "pepper' and "white album". I would also recommend "The John Barrett tapes" as 'core', and I know you said you don't want anything 'repetitive' but "It's not too bad" is one of my all time favorites (it's pretty much the complete evolution of Strawberry Fields Forever from the Santa Isabel demos, to home demos to multiple takes at Abbey Road. It's arguably the most enlightening Beatles disc I have ever heard)
