As versatile as the Kronos Quartet, and smoother than the Brodskys, The Smith Quartet have edged ahead of their competitors in contemporary chamber music. In 'Ghost Stories', Tim Souster's Hambledon Hill moves from skittering glissandi to a unison of striking intensity, echoed in Stephen Montague's String Quartet No 1, while Michael Alcorn's eerie The old woman of beare has whispered into nations over skeletal harmonies. Though brilliantly played, Gavin Bryars's The sinking of the Titanic is the weakest work and, at just under 15 minutes, seems to last as long as James Cameron's film.
