Still catching up on posts from this past week, but couldn't let the night pass without a call-out to Brad Mehldau's set tonight at the People's Symphony. On a stage that normally features the likes of pianists Richard Goode, Emanuel Ax and Leon Fleisher, Mehldau - a good thirty years their junior - more than held his own. (He, like his elders, also managed to sell out the Washington Irving H.S. Auditorium.) Mehldau alternated virtuosic flights with tender ballads, performing unapologetically melodic arrangements of everything from Sonny Rollins and Antonio Carlos Jobim, to Elvis Costello ("Baby Plays Around") and Sufjan Stevens ("Holland"). An arrangement of Richard Rodgers' "My Favorite Things" sounded like Schubert's D-minor sonata, somber and symphonic. His own composition, "Trailer Park Ghost," was a 10-minute, nonstop blur of trills and arpeggios. Occasionally, Mehldau was a bit pedal-heavy and flirted dangerously close to George Winston territory, but kept it real with dissonant chords and spiky rhythms. If you missed him tonight, you can catch him with his regular trio all next week at the Village Vanguard: door is $30, plus a $10 minimum.
