Not only is the music from the show absolutely brilliant but the quality is outstanding. Considering it was recorded in the 60's, the remastering is a top aspect here. Now looking into the contents of the CD case, I found it interesting reading about Barry Gray and another story in the booklet. The description about each of the tracks is good as well.
The tracks that stand out for me are the instant-recognisable 5, 4, 3, 2, 1 Thunderbirds Are Go! (Main Titles) as it always brings a smile to my face remembering that classic opening. The dramatic 'Fireflash landing' and 'Monorail to Disaster'. 'Thunderbirds are go!' which is used for when TB1 and 2 are getting ready to launch, mainly the Thunderbird 2 part is my favourite out of the whole CD. The Jazz pieces 'Dangerous Game' and of course 'The Man From MI5', it's also a pretty snazzy title for a song.
I would recommend this to someone who's music interests are soundtracks or orchestral as s/he will love it!
