In the early ‘70s Frank also worked to provide music for The Yates Theatre Group (‘At the Hawks Well’) and The London Theatre Company (Steven Berkoff – production of Agamemnon) and with dancer June Marsh plus the improvising dancer Shelley Lee. In 1978 Frank invited the ex-Eurythmics flautist Tim Wheater to join him for a duet at The White Eagle Lodge HQ London and later at the Festival of Mind, Body & Spirit at London’s Olympia. In 1982 he met David Hykes and Alain Presencer in a shared public performance of solos followed by an improvised trio arranged by entrepreneur Richard Temple (of the Temple Gallery). Having thus befriended the Tibetologist Dr. Alain Presencer (specialising in Tibetan singing bowls, horns, and vocals) they swapped instruments and shared several performances. In the summer of 1982 David Hykes (stunning exponent of harmonic singing and founder of The Harmonic choir of New York) arranged for two evening performances as part of the Almeida Festival, featuring solos by both artists followed by an improvised duet. Whilst performing and taking workshops at Oak Dragon Camps in the eighties and early nineties he also provided the music for ‘Psychic Dance’ with Colin Harrison and Sue Barnett (a leading shamanic practitioner / psychic in Glastonbury), and he also worked in a duo with pianist composer Lawrence Ball. In 1972 he joined The White Eagle Lodge choir singing bass and, as previously mentioned, soon went on to introduce voice into his solo performances. He discovered in 1973 that he could immediately perform the extremely difficult vocal technique of the Tibetan Tantric School – the famous Gyudto chanting – and in 1980 similarly found an instantaneous ability to execute the additionally demanding vocal technique of Mongolian overtone singing and he has incorporated these into his music ever since. In the early 90s he collaborated with composers Jenny Roditi and Maxwell Steer alongside musicians/teachers Bill Martin (formerly of Pyewacket) and Susan Nares in a group exploring overtone singing initially called Enchanter.
