I agree with DrumBob and Rocky regarding Lynne's production. His solo stuff, his production of Tom Petty, George Harrison, and the Wilburys, they all have the same sound.
I really liked the first two ELO albums, Eldorado and Face the Music. In an interview with Rolling Stone decades ago, John Lennon casually trashed the group as "son of 'I Am the Walrus,' ". This may explain why I liked them when they first came out! Then it got to be too much of the same thing for me after that. I was working at a record store when "Out of the Blue" came out. It sold a lot of copies, but we didn't really even want to play it.
I saw them live in 1978, with Robin Trower opening. After Trower, they were pretty boring. This was the year they were accused of lip-synching by a promoter.
Lynne is clearly more of a producer than a performer, and he has produced some huge albums, that's for sure.
