sentences:  Glackin has since released numerous recordings, including seminal ones such as "Doublin" (1978) with the piper Paddy Keenan and "In Full Spate" (1991) with Dónal Lunny.More recently, Glackin recorded the duet album "Seidean Si" (1995) with piper Robbie Hannon, and "Reprise" (2001) with his former Bothy Band colleague, the late Mícheál Ó Domhnaill.Although Glackin is quite outspoken in his preference for a pure soloist approach to the tradition, he has been involved in a number of experimental recordings, including "Roaratorio" by the American avant-garde composer John Cage and "Hidden Ground", a recording from 1980 made with the late multi-instrumentalist Jolyon Jackson which is notable for its use of synthesizers alongside Glackin's pure traditional fiddle playing.
