Disc 1 of this 2 (3 if you've also got the limited edition BBC Radio Theatre June 2000 concert) CD set is interesting as an historical record of early Bowie. Songs from his Anthony Newley period, Space Oddity and Man Who Sold the World are featured but it's the ballsy version of Chuck Berry's "Almost Grown" and an unreleased Bowie track, "Looking For A Friend" which are the tracks you'll come back to on this disc.
What makes this collection an essential Bowie purchase, however is disc 2.
Practically the whole Ziggy album was re-recorded live in the studio for the BBC at various times in 1971 and 1972. And it's an unrestrained, rawer and more dynamic Bowie and the Spiders you hear. Standout tracks include "Suffragette City" and "Moonage Daydream" - pure voltage compared to the studio album.
The pieces de resistance on disc 2 are Lou Reed's "White Light, White Heat" and "Waiting For The Man". Bowie and the Spiders recorded several versions of these for the BBC. Take it from me, the versions included on this collection are the best - Bowie has almost made these songs his own.
Check out, too, the Velvet Underground pastiche "Queen Bitch" and another Hunky Dory track, "Eight Line Poem" which is more beautifully delivered than the original studio version.
And at last on CD is the excellent, mostly acoustic, version of Space Oddity recorded for the Johnnie Walker show in 1972.
Some real gems on this long awaited collection - and a perfect tribute not only to Bowie but to the talents of ace guitarist and arranger Mick Ronson.
