It takes a pianist with “epic technique … superhuman speed, power, and agility” (The Boston Globe) to successfully embrace Liszt’s flash and Scriabin’s exotic harmonies. Denis Matsuev is just the artist. Liszt’s Sonata unfolds in one massive movement with a deliriously virtuosic central section and whispering finale, while his Mephisto Waltz No. 1 is a rollicking showpiece. Scriabin’s music fascinates with its progressive harmonies—particularly in the Fifth Sonata—but also makes significant demands on the performer’s technical skill, like in the tumultuous finale of the Sonata No. 3.
