Although the remastered reissues claim to feature 2 bonus tracks they are NOT bonus tracks to the original CD release, on GWR, in 1988. That featured two tracks - 'Stay Clean' and 'Metropolis' - additional to the LP and cassette version but had them in their rightful places in the set ('Doctor Rock/ Stay Clean/ Traitor/ Metropolis') and not tagged on to the end of the LP version, which we have here. In addition, the artwork in the reissues is likely taken from the GWR CD booklet rather than the original: it is thus a little fuzzy and scaled down in comparison, although it does add some contemporary press clippings. The reissues may be remastered but my ears can't hear it on this particular title and personally I've yet to be convinced that any album needs a remaster when it had a contemporary release, 'Orgasmatron' being Motorhead's first CD release for a new album. Generally Essential/ Sanctuary have done a great job on the reissues of the back catalogue, particularly the new 2CD sets with live tracks and BBC archive material, but this is their weakest effort and I would suggest tracking down the original. In terms of SQ, I personally hear no difference between the original and the remaster.
