Capricorn was a mixed chamber ensemble based in London and active in the 1970s, 1980s and 1990s. Founded by the cellist Timothy Mason, clarinettist Anthony Lamb and pianist Julian Dawson-Lyell (who took the name Julian Jacobson in 1983), the original lineup was augmented by the violinist Monica Huggett to perform Messiaenʼs Quartet for the End of Time which featured in their London debut concert at Wigmore Hall in January 1974. Following the death in 1997 of Timothy Mason, who had acted as the groupʼs unofficial artistic director, the group wound down its activities.
