In 1965 a French Government grant took him to France to study with Ida Presti and Alexandre Lagoya.
He studied composition with James Patten, Elisabeth Lutyens and Hans Keller, as well as widening and enriching his musical knowledge by working with non-guitarists Anthony Kinsella (piano) and Vic Bennett (clarinet).
Biberian has played at the Proms, at Covent Garden and has performed concertos and given solo recitals worldwide.
New works have been written for and/or dedicated to him (for solo and ensemble) by James Patten, Elisabeth Lutyens, Reginald Smith Brindle, Alfred Nieman, Charles Camilleri, David Bedford, Roger Williams, Glen Morgan, Robert Keeley, Jeffrey Joseph, Kenneth Paige, Daniel Sturm, Vojislav Ivanovic, Betty Roe, Ivor Mairants, Geoffrey Burgon, Aurelio Peruzzi, Judith Bingham, Monique Cecconi-Botella, Ottavio Negro and Luis Morales Giacoman.
In addition to his pioneering work in chamber music, and always in search of exciting possibilities for the guitar, he expanded the role of the instrument by combining with mime in three works, "Pierrot", "Harlequin's Toccata" and "Colombine", which are now successfully established as stage and concert pieces.
