Here is music from my friend Jean-Paul Verpeaux again. This piece is an imitation in minor mode of JS Bach's toccata bwv 540.
French composer and organist Jean-Paul Verpeaux (b. 1951) was born in Paris. He has composed more than 300 pieces, primarily for the organ. Verpeaux began playing as a church organist at age 16 and pursued it for many years alongside a primary career as an electronics engineer for the French Air Force. During these years he composed music for a number of military films and taught electronic music at the music academy in Chinon. He had planned to spend his retirement by returning actively to organ performance, but a diagnosis of Parkinson’s disease prevented him from returning to live playing. However, Verpeaux has remained active as a composer of works for others to play and but creating virtual organ performances with software, including several programs he has developed himself.
