"In everything she does, there seems to be a special combination of utterly self-assured virtuosity and real lyricism," wrote Tom Service of the Guardian.

Reviewing Lisitsa's Albert Hall debut, Telegraph's Ivan Hewett wrote she "played these with urgent intensity and a feeling for their sudden moments of pathos."

"It soon became clear Lisitsa is a serious artist. She'd chosen a hugely taxing programme, book-ended with two Liszt showpieces," Hewett noted.

Stephen Smoliar, Examiner's classical music connoisseur, notes that Lisitsa "certainly managed to cover a broad expanse of music history, from Wolfgang Amadeus Mozart's K. 475 C minor fantasia all the way into the twentieth-century works of Sergei Rachmaninoff."

While praising Lisitsa's talent, Smoliar noted Lisitsa "may need to cultivate some appreciation for the proposition that there can be too much of a good thing," hinting that the program may have been too long for "even the most persistent listener."

In contrast to Smoliar's observation, some of those who claim to have watched live hinted the audience remained captivated by Lisitsa through "several encores."

"She certainly charmed the audience verbally with her candor (telling with gratitude the story of how she came to be performing here), and more importantly with her expression of deep musical feeling and stunning virtuosity. This includes not only the more intense pieces like Liszt's Totentanz, but in many slow, clearly heartfelt gentle pieces in the program and e.g. first encore," a Telegraph reader commented.

The entire concert was recorded, and classical music enthusiasts could get in on Amazon. The concert CD will be released on July 24.
