Trio Solisti, Pictures at an Exhibition. The “filler” is the highlight: a flawless performance of Ravel’s luscious A Minor Piano Trio by the group that to my mind has now succeeded the Beaux Arts Trio as the outstanding chamber-music ensemble of its kind. The main event is an ingenious arrangement of Mussorgsky’s masterpiece by the members of the trio. It’s fun to hear but ultimately inessential–all Pictures needs to make its effect is a single pianist. The Ravel, on the other hand, is worth twice the price of the album all by itself (TT).
