The Stena Suite by Simon Paul Austin (Opus 5 Nos. 1-11) consist of eleven short string quartets that are each three or four minutes long.  They are melodic and cover a full range of emotions, being fun, curious, mischievous, contemplative and sad.  All four members of the quartet enjoy interesting parts making them enjoyable for each member of the quartet.  They can be performed as a complete set or combined ad hoc to create an interesting program for performance.  They are great to play and great to listen to.  Get them here.
