Buckley was a key member of Loose Tubes. He has also been an important side man in many bands including, Human Chain, Ashley Slater's Microgroove and Django Bates' Delightful Precipice. A close connection with African and Latin American musicians led to his playing and recording with such bands as Bosco D'Olivera's Grupo Folia (UK), The Pan African Orchestra (Ghana), Kakatsitsi (Ghana) and Massukos (Mozambique). One of his closest musical associations is with trumpet player Chris Batchelor. Together they released three albums, "The Whole and the Half" (1995), "Life As We Know It" (1999) and "Big Air" (2008), the latter featuring Oren Marshall, Jim Black and Myra Melford.
