Matt Hare commissioned Stratum in 2014 in memory of his father, Gregory Hare. Hayk Arsenyan and Hare premiered Stratum at the 2015 International Society of Bassists' Convention in Fort Collins, Colorado. It was very well received and has been in play worldwide since 2014. It's an intricate, thoughtful piece written for Double Bass and Piano, with a decidedly contemporary feel. Duration - 16mins.
