Love overthinking this question on a number of levels.
Do lineup changes matter and do official live releases versus bootleg material factor in.
For instance, if you pick The Grateful Dead do you get a large quantity of official live releases, and do you get Dead & Co. (John Mayer) live output?
If you pick Fleetwood Mac, do you get both the Peter Green era and the Lindsey and Stevie era?
Do you get Peter Gabriel Genesis and Phil Collins frontman Genesis?
King Gizzard would be an interesting pick, in say five more years time, as youāll probably have 100 albums to choose from.
