Gorecki is most famously known for his 3rd Symphony of “Sorrowful Songs”  and for what has been termed holy minimalism: simply, austere and serene.  But in the 60’s Gorecki was an avant garde  contemporary composer writing quite different pieces.  The work in the following video is his Sonata for two violins.  It is not a billboard chart topper like his 3rd Symphony, certainly with less mass appeal,  but it is a contemporary piece well worth checking out.
