Deep Purple were a legendary band when I was at school but didn't fit into my Grammar schoolboy interests and so I never got into them, then. Now, thirty plus years later, I only have one DP recording - this one, so I'm not pretending to be enough of a fan that I'd buy everything they ever produced.
However, when I do want some Deep Purple, this fits the bill perfectly and to my pleasant surprise was consistently good, despite the 3 CD length. Yes, I like the classics best, with Child in Time my favourite but here there's also far more to their repertoire, they certainly didn't always sound the same. You could play all 3 discs all the way through or put them on random and you wouldn't be bored.
At around less than a fiver, now, this Platinum Collection has to be one of the biggest bargains in rock music.
