This is a brilliant selection of many of the unearthly sound effects which were so essential to the success of the 60s Doctor Who adventures.
Highlights must be the superb swirling Dalek City sounds, the full TARDIS take-off and the various versions of the original "Who" theme tune, but there are countless other atmospheric tracks. Radiophonic Workshop "guardian" Mark Ayres has done a fantastic job in finding and restoring these cues to their present quality. There are also a few tantalizing segments of Dudley Simpson's early incidental music using the BBC's electronic organ and synthesizers.
Forget the repetitive and unimaginative sounds of Star Trek: The Next Money Grabbing Franchise, these are truly the most original and otherworldly special sounds you are likey to hear.
I highly recommend this release, and also its sequel, volume 2!
