DEEPEST PURPLE - THE VERY BEST OF DEEP PURPLE

I remember listening this compilation as a teenager at one guy's home where me and my pals used to hang around. I recall this gave me a very limited view to the band, as it has only their basic, most accessible hard rock songs in it. At least "Child in Time" made a good impression to me, so I checked out their records from the library and found their Simper era material, which wasn't represented on this compilation at all. Surely this is from the deepest of depths.
