With this remarkable three-CD collection of Arthur Foote’s complete piano music (much of it recorded here for the first time), Ms. Johnson has filled a long-standing gap in the global discography of this very worthwhile American composer’s music. Foote was a prominent member of the so-called “Boston Six,” a highly influential group that included fellow composers Beach, George Chadwick, Edward MacDowell, John Knowles Paine and Horatio Parker. Much of their music has yet to gain the exposure it deserves, as its strong European roots has led the musical establishment to unfairly dismiss it as lacking originality as well as true American sound and spirit.
