Alex Freeman found initial inspiration for his string quartet (2015) in a series of photographs a geologist friend showed him of en échelon veins in rock formations. The open strings punctuated with pizzicato unisons that begin the single-movement work call to mind something crystalline and shimmering, which is immediately infused with tumbling lyrical lines in something of a rapid caccia technique throughout. The middle of the work becomes more suspended in slower material loosely based on a technique of prolation canon, comprises layers of free, expressive, lyrical, and even elegiac music moving at different speeds. As the work concludes, the materials converge in a rhythmically pulsating stasis and an almost chorale-like statement.
