From among the many British string quartets that cultivate the repertory of the Classical period, the London Haydn Quartet stands out for its use of period instruments, strung with gut and played with bows from the Classical era. The group often but not exclusively performs the music of its namesake. The members of the London Haydn Quartet -- violinists Catherine Manson and Michael Gurevich, violist John Crockatt, and cellist Jonathan Manson -- came together in 2000 after discovering their mutual enthusiasm for Haydn's music; the membership has remained constant. It has also collaborated, on recordings and in concert, with period-instrument clarinetist Eric Hoeprich, with whom it recorded the Brahms and Mozart clarinet quintets in 2007. At the center of its recorded output, however, has been its cycle of Haydn quartets; the series concluded in 2023.
