The zombies have not been neglected on CD but if you are a true fan this is the only collection you should consider.  It contains virtually everything the group recorded for both DECCA and CBS.  The sound quality is superb, although I was initially disappointed that the DECCA material was  not in stereo, having stereo mixes on other CDS.  However, after reading  the excellent booklet notes by Alec Palao, I accept that mono is the way  these tracks should be heard. (the Decca material has since been issued in wonderful stereo on a 2CD collection & is also essential for fans).  Listening to songs like "what more can  I do" and "summertime" convinces me that the Zombies were  one of the 60's best groups. "I remember when I loved her" sounds  like it was recorded in a graveyard at midnight,with ethereal organ and  tambourine which sends chills up my spine. There are so many great tracks,  including many unreleased until now, that it is amazing that the group had  so few hits.
