Genesis - The Lamb Lies Down on Broadway (50th Anniversary edition)
As far as I can tell, this is a 2025 Remaster on Blu-ray of the original album, plus the entire album concert from 1975 (also remastered) which previously featured in the 'Archive' boxset in 1995.
The original album sounds great, but is not hugely different to the previous version. The live album is absolutely fantastic, albeit Peter Gabriel's vocals were apparently largely rerecorded in '95, which is very noticable, even to someone who hasn't heard the live album before (like me). The end result, however, is still super-impressive - it shows just how great a live act Genesis were in their prime just before PG left. It's a pity, however, that PG's original vocals are mostly gone, as he has always been an incredible vocalist - however, 'The Lamb...' tour was plagued by technical issues and the original recordings apparently didn't do justice to the vocals and some of the guitar work, hence the overdubs.
I once saw a documentary where Phil Collins explained that the live show was so complex (with slides, film and lighting synced to the live music) that it never worked perfectly, and also the tour was never filmed so there is no high quality footage of the tour, which is a great shame - all the more reason, however, to enjoy these recordings.
