Many musicians swear by pianist Kenny Werner’s groundbreaking book on improvisation, Effortless Mastery&...#8212;Liberating the Master Musician Within (1996). In 2010, Werner produced the acclaimed album No Beginning No End, a profoundly touching tribute to his late daughter, Katheryn. On this 2007 Piano Jazz, Werner and McPartland get together on a pair of Bill Evans tunes, “Very Early” and “Waltz for Debbie.”
