Deepest Purple was my very first Deep Purple album. When I first listenedto it I was astonished by the bands musicianship. The tracks are all ofthe Mk 2a era except tracks 9 and 11 wich are Mk 3. I would say thesesongs represent this era probably the best, altough i do miss Fools andMight Just Take Your Life, but you can't get everything. Altough there areno bonus live tracks on this best of compilation, there is a remix ofSpeed King and probably of some other songs altough I can't hear exactly,wich should tempt for older purple fans who already have everything worthhaving. For beginners wondering what deep purple is, this cd is perfect.Buy it if you don't have any deep purple, or if you have everything else.
