First appearing on TV screens in September 1968, Joe 90 was a unique nine year old boy with the ability to absorb the brain patterns of top experts enabling him to become the most special agent of W.I.N. (World Intelligence Network). Whilst there are arguably better-known scores amongst Barry Gray's sublime catalogue of work with the Andersons, the composer's work for Joe 90 is in many ways the most consistent and inventive selection he ever wrote. Developing a theme for the new series was always the musician's starting point, and for Joe 90, the pop charts breezed into Gray's studio, with an opening tune featuring a genuine groove. Mixing Gray's inventive electronics with 60s "surf rock" guitars was an inspired decision. It is no wonder that this piece has gone on to enjoy a second life as a Northern Soul disco floor-filler. For episodic incidentals, Gray was freed from the detached unearthly premise of Captain Scarlet and able to bring back a playful sensibility and a more mature musical palette which are amply illustrated in this 24 track collection.
