Flux is Signum’s second disc with the contemporary music ensemble Lunar Saxophone Quartet. A saxophone quartet is by necessity a group that relies on new repertoire and compositions, lacking the historical treasure-trove of works available to groups such as string quartets. As a result LSQ have become a championing force for new music and compositions. This disc of the group’s commissions combines the works of established composers such as Gabriel Jackson and Michael Nyman with others by contemporaries of the group – a ‘flux’ of styles and influences from a group who seek to create music that is “accessible, without compromise”.
