“How does one review a monument?” Richard Crawford wondered when he sat down to review the first AmeriGrove in 1987; it puts “the conventional notion of a review to the test.” Some thirty years later, with the new AmeriGrove twice the size of the first edition and with the U.S. soundscape becoming more global and hybrid by the day, the challenge has increased for the potential reviewer. Indeed, how do you review a collective enterprise with up to 1500 authors and 9300 entries (some old, some new) along a timeline of some 350 years? For a professional insider like Richard Crawford the test was tough enough, but to assess its virtues and faults from a European perch, it is positively daunting, particularly when post-national, global crosscurrents continue to inspire a constantly evolving U.S. musical scene.
