Our Team

Isobel Griffiths

Founder

Entering the music industry in the late 1970s Isobel started out as personal assistant to the composer Jeff Wayne and after a year or so she started a division at Jeff Wayne Music called The General Booking Company which were Contractors/Fixers for TV commercials, TV dramas, artists’ singles and albums. In 1985 she started her own company simultaneously working part-time for the composer George Fenton in an old warehouse in Chelsea next to The 606 Jazz Club housing herself, Alice (her German Shepherd), George and his 7ft Bösendorfer piano.

A year later, George and his piano moved to central London (Alice is still blamed for this) but, all thanks to George’s faith, friendship and loyalty Isobel was now ready to survive on her own.

After more than 40 years guiding IG Ltd and with over 11,000 film scores, TV scores, video game scores, albums and singles undertaken, Isobel has transferred the shares of her company to a fellow, highly respected contractor and friend: Hilary Skewes. Throughout the course of 2026 Isobel will still be in constant touch with Hilary, Susie Gillis (CEO) and the entire dedicated team of fixers here…. and in 2027, who knows, maybe time for another Alice.

Hilary Skewes

Director

After studying English Literature at Cambridge University, followed by two years studying musical performance (MA) at Mannes College in New York, Hilary started out her professional career as a freelance cellist, gaining first hand experience of life on the “other side” of the glass. She spent her twenties performing in classical orchestras, sessions, quartet gigs, with Madonna, George Michael, Robbie Williams, on Top of the Pops, TFI Friday, Later with Jools Holland …..a long list of amazing artists and experiences.

Hilary’s natural organisation skills (bossiness?) found her leaning more towards arranging projects rather than just playing in them, and she finally started her own contracting company in 2000.

In a recording studio of seventy musicians every single player counts equally towards the enchantment. Hilary’s passion is matching players to a score, finding the combination of talent and character that allows the performance to shine. This, in combo with a fierce attention to detail and almost infinite patience, has allowed Hilary to work successfully on countless film, TV, video game, audio and live recordings over the years.

With Isobel deciding the time was right, Hilary is honoured to be stepping up to try and fill her shoes. IG Ltd has been the gold standard in fixing/contracting in the UK for decades, and as a team we plan to keep it as such.
