Cuban pianist Harold Lopez-Nussa’s new, celebratory album, El Viaje (The Voyage) surges with such an abundance of inspiring exuberance, pyrotechnical brilliance, fiery passion, luminous lyricism, rhythmic propulsion and crackling keyboard clarity that you just can’t believe the phenomenal, 30-year-old virtuoso from Havana when he confesses that he was “terrified and a bit shaky” when taking his first giant steps from classical music to jazz.
