Classical string orchestras and chamber music ensembles are constantly looking for jazzy and popular works which break through the boundaries between serious and light music. On the basis of his own practical work with string orchestras, the well-known jazz composer Sigi Busch has written two fantastic pieces for open-minded string players. They deal with the blues while also leaving room for the player's own improvisations. They are of moderate difficulty and suitable for good school orchestras, chamber orchestras or string quintets.
