The "re-performance" of Glenn Gould's 1955 recording of Bach's Goldberg Variations on the Zenph Studios player piano (which is to say, a recording of a reproduction of a recording), which debuted on the chart a week ago at no. 2, has slipped to no. 5.

Welcome to the Voice, a rock-classical fusion oratorio composed by Steve Nieve (the former keyboardist for art-rocker Elvis Costello) and performed by Costello, Sting, soprano Barbara Bonney and the Brodsky String Quartet, fell to no. 10 after entering the previous week's chart at no. 6.

On its way up is pianist Jon Nakamatsu's all-Gershwin disc on Harmonia Mundi, which rose from no. 21 to no. 13 in its second week on the chart. The recording, which includes the Piano Concerto in F, Rhapsody in Blue and the Cuban Overture, also features the Rochester Philharmonic Orchestra under conductor Jeff Tyzik.

Cellist Yo-Yo Ma's Appassionato continues its run at the top of the chart. With the Gould/Zenph Goldbergs having fallen three notches, Joshua Bell's Voice of the Violin is back at no. 2, followed by Sting's Songs from the Labyrinth (lute songs by John Dowland) and Lang Lang's new disc of Beethoven's Piano Concertos Nos. 1 and 4 with Christoph Eschenbach and the Orchestre de Paris.

The top of the Billboard classical crossover chart is exactly as it has been for the past month or so: Josh Groban's Awake at no. 1, followed by two discs by the operatic boy band Il Divo (Siempre and Ancora), three titles by blind Italian tenor Andrea Bocelli, and the Mormon Tabernacle Choir's Broadway tunes album, Showtime!. At the other end of the chart, two released returned: Love, from Italy by Andiamo (an Italian equivalent of Il Divo), at no. 25, and Here's to the Heroes by The Ten Tenors at no. 24.
