Fresh off a brutal travel swing (Paris, New York, Bogata and Washington in two days), the gifted — and presumably well-caffeinated — French pianist Lise de la Salle took the stage at the Phillips Collection on Sunday afternoon for a program devoted to the terrors and joys of love.

A prodigy who made her concert debut at the age of 9, de la Salle has developed in her 20s into a musical thinker of impressive weight, with charm, imagination and a dazzling technique. And while all that was amply evident Sunday, it seemed to take de la Salle a while to settle into the emotional depth of the music. Opening with three transcriptions by Liszt of love songs by Schumann and Wagner, de la Salle turned in big, sweeping readings that, for all their virtuosity, felt rather dry-eyed — declamatory rather than seductive, lush but rarely rapturous, detailed but lacking in tenderness or mystery. Maybe it was just understandable exhaustion. But as love goes, it all felt a bit clinical.
