Although ELO had reasonable success prior to this album, this is the one that made them huge. This is my third purchase of this album; LP, first issue CD and now the wonderfully remastered version. I recently played some of the first issue ELO CD's and found that they sounded a bit flat, in this day and age of remastering. So I thought I would cherry pick my favourites of which this is one and to convince me to part with further cash, they're all currently at good prices. I am not disappointed as the songs all sound fresh and bright. The bonus tracks are worth a listen if you're a keen ELO fan, as four of them are instumental versions, in other words the backing tracks without the lead vocals. They do give you a greater insight into Jeff Lynne's genius. There is also a slightly different version of Telephone Line, which makes for an interesting listen. There are many stunning songs on this album, but I think the first and last of the original nine tracks are my favourites, those being Tightrope and Shangri-La. Classic!
