This complete six CD collection of Hollies output between 1963 and 1968 is obviously a must for collectors, and for me it was a great way to once again hear those those much loved and elusive songs - like the fabulous "Baby That's All" But what is most interesting, is the way the material - thankfully presented in chronological order of recording - shows how the band begins to lose it's way towards the end of the Nash period, and how work that Nash would later go on to create with Crosby Stills and Nash begins to creep in, like the wispy and fey "Butterfly" on CD 6. But, unlike The Everly Brothers, who harmonised with a cadence and feeling, those fabuluos Hollies harmonies do somehow lack subtlety, and sometimes have a "just listen to this one - it's a real belter" quality about them, that becomes tiresome in large doses. But the figures show that this was one of the most successful British bands of all time, and this great collection shows just why they were a huge part of the sixties. Great value and good listening. It made an old rocker very happy!
