This 2 DISC DELUXE EDITION. I do not think this edition is for everyone. Serious Blackmoe/Dio collectors would want this, but if money is tight (and it is for most of us) you may want to keep your previous remaster. Casual fans wouldn't need this version. The reason I bought this was for the "Rough Mix" of "Rainbow Eyes." Without the overdubs it is a very "alone" and poignant sounding which has extra significance with the passing Of Ronnie James Dio. The remastering is ok/good, a bit more top- end clarity, but it is no revelation. The extra top -end may bother some, but remember Rainbow were never recorded that well in a technical sense. Martin Birch was awesome but the band often recorded in unconventional places. The very first Rainbow album was recorded better than the several that followed. Although that first album was recorded very dry and was a bit under-produced. The extras here are "ok" so it's really a matter of do you want the extras and the slightly better mastering? I find it to be an improvement over my Japanese Mini LP version (especially on the drum sound) but the bass, like on many Rainbow albums, lacks clarity and definition. The most noticable differences on the extra mixes are the intro on "Lady of the Lake", the sparse "Rainbow Eyes", and the more noticable bass lines on "kill the King". You are not going to get any substantial or new Blackmore solos on the extras. Where there are new Blackmore solos they are a bit buried in the mix. I cannot believe they included those "Don Kirshner" tracks!?? I believe those are just Ronnie singing live over a studio backing tracks! (With alot of reverb on the vocals) The liner notes are okay, with a few stories about the haunting of the studio. I am still confused by what exactly happened with Marke Clarke as these notes still do not clarify. Packaging is the same as the previous Rainbow Deluxe Editions. The lyrics are included which is nice too. Note: I paid less by purchasing this from "AMAZON UK" and received it sooner as well. For me it is worth $22 but Not $28. At the current price of $17.22 it would be even more worth having. If you were happy with the other Deluxe Editions of Rainbow you should be happy with this one. Those who were not happy won't be happy with this. I hope the series continues as there may be more bonus material on the later-day Rainbow albums. I'm not blown away by this edition but am glad I have it. For me, "Rainbow Eyes" was the real gem. **Update. No way to confirm this, but according to an article on the Rainbow fanclan legacy site Blackmore plays bass on the "rough mix" songs and Tony Carey is on Keys.
