Jeff Lynne's both solo albums Armchair Theatre and Long Wave, the ELO titles Electric Light Orchestra Live and Zoom and the Jeff Lynne's ELO titles Alone In The Universe, Wembley or Bust and From Out Of Nowhere - will be re-issued in a Mini-LP CD formats. ELO Live, Armchair Theatre and Zoom are already Mini-LP, but now the others will follow. All titles will be uniform now.
In addition, ELO's main Sony catalog will be joining them from 1973's On The Third Day, 1974's Eldorado, 1975's Face The Music, 1976's A New World Record, 1977's Out Of The Blue, 1979's Discovery, 1981's Time, 1983's Secret Messages (will supposedly be the 2018 'double LP' version) and 1986's Balance of Power.
Edit: I'm going to suspect these CDs will be void of any bonus tracks.
All of these CDs will have a fresh 50th Anniversary obi on them.
That's the good news. The not-so-good news is that ELO 1, ELO 2, Long Beach, and Xanadu, as well as any compilation (Ole ELO, ELO's Greatest Hits, Flashback, etc) will not be taking part. This does not bode well for the future.
These are all slated for an August 25, 2021 release.
