Timo Andres is a fastidious generator of beauty. Most obviously it is musical beauty, as Andres, a composer and pianist who is not yet 30, is a prodigy who was improvising on songs at the age of 6, graduated from Juilliard and Yale, has a full plate of commissioned works, and has released two albums that have provoked comparisons to John Adams and Charles Ives.

His second record, last year’s “Home Stretch,” boldly fills in the absent left hand of Mozart’s “Coronation” Concerto and also offers up a 14-minute “Paraphrase on Themes of Brian Eno.”
