The Electric Light Orchestra and I go back in time buying the 45's back in the day and later on getting a good number of their albums on cd.
Like with a number of other artists, recently their has been an attempt to bypass some of restrictions of conventional cds, a technology that goes back the late 1970's by issuing in higher resolution 24 bit downloads and I obtained a number recently.
When it comes to compilations there's been a good number starting from 1979's Greatest Hits that in some ways is remains the perfect summary of the 1973-77 singles and double or even triple cd sets.
The one I remember getting in 1997 was Light Years a mid price British double which was jam packed full of material including edits, in no particular order and suffered from being too consistently loud and bright so I relented and got the original Greatest Hits album on a cheap cd.
That did leave missing a selection of the later hits as most miss off anything from the Zanadu soundtrack that gave us three hit singles and to which the title song had been re-recoded in 1991 for the Flashback cd box set that was criticized for it's sound quality and chopping off the very start and ends of a number of tracks.
The one pictured above most would consider the best of the bunch having most of the essential tracks including the very early tracks and was very well mastered by Vic Ansini in 1995 who did excellent work on a number of Columbia projects like the Simon & Garfunkel remasters.
It was only issued in North America and recently I've ordered a copy to fill those gaps and having the European Zanadu soundtrack, the missing tracks from it aren't so much of an issue with me.
