No Boundaries, the second album from the quintet of piano-playing siblings, has been at number one since its release three weeks ago. The group's self-titled debut, which had previously dropped off the chart, has ridden the coattails of the new album up to number three.
Pianist Lang Lang's Memory remained at number three.
Among the albums enjoying increased sales this week were Plšcido Domingo's Italia, Ti Amo, a collection of Italian popular songs, which moved from number 13 to number 10 in its third week on the chart. There were no new entries.
The classical-crossover chart was similarly static, with Andrea Bocelli's Amore remaining at number one, followed by Il Divo's Ancora and Il Divo. Amor, the Spanish-language version of Bocelli's album, is still at number four.
The sole new entry was Strung Out On Taking Back Sunday, the latest in a series of string-quartet tributes to rock bands, at number 24.
