Solo ultimately reveals little we didn't already know about Vijay Iyer as a pianist, but to hear him explore these facets of his sound on his own, with no one to lean on, is still interesting. The central suite is where the album and the artist truly shine.
He can clearly make a piano do just about anything he wants it to, and Solo is a project that puts the thought that went into its construction right up in your face, but it's never breathtaking in the way a truly great solo piano performance can be.
To make so many overt references to his musical heroes while never losing sight of himself speaks to Iyer's own command. His improvisations have such clarity and vision, and it's rare that he stretches things any longer than necessary.
