ITV's Thunderbirds Are Go is now shown in more than 40 countries worldwide. The series has enjoyed strong international recognition since its launch in 2015,50 years after Gerry and Sylvia Anderson's classic Thunderbirds series was first broadcast. Ben and Nick Foster have made it their business to deliver new music for this groundbreaking series. Faced with the daunting task of following the footsteps of the original and productive Thunderbird composer Barry Gray, the duo has followed the same path with a full symphony orchestra, adding modern accents to bring the sound up to date, but maintaining the reverence for the original.
