Album of the Week: Henning Kraggerud - Equinox

This week's album pick is "Equinox" with Norwegian violinist and composer Henning Kraggerud and the Arctic Philharmonic.

This album is inspired by philosophers and composers who have discussed the link between musical keys and time and space.  Equinox consists of four concertos - Afternoon, Evening, Night and Morning.  Each concerto consists of six postludes, making 24 in all.  These 24 postludes are written in 24 keys and depict 24 hours and 24 time zones.
