Sara Bareilles’ ‘Heart’ opens at No. 1

Overall number of discs sold last week is lowest ever

Sara Bareilles’ sophomore major label album “Kaleidoscope Heart” became the thrush’s first No. 1 album on the U.S. chart last week.

Four new albums debuted in the top 10, but numbers were the dreariest ever. Frame’s tally of 4.83 million total units sold was the lowest since SoundScan began tracking sales in 1991, according to Billboard. The No. 200 album on the chart, the National’s “High Violet,” rang up a meek 2,500 copies.

Northern California-born thrush Bareilles’ Epic release sold 90,000 copies, according to Nielsen SoundScan figures for the week ended Sunday, Sept. 12.

Her collection is the first album to hold the top slot on the chart with less than 100,000 sold since June, when the “Glee” set “Showstoppers” did the trick with a 63,000-unit week.

Eminem’s ongoing hit “Recovery” (Interscope) fell one slot to No. 2 with 81,000 sold (off 12%), but rapper can expect a lift again next week following his opening slot on the MTV Video Music Awards and wide press coverage of his Yankee Stadium show with Jay-Z.

The Capitol-distributed “Now 35” hits package dropped one rung to No. 3, with 63,000 shifted (off 40%). Katy Perry’s chirpy “Teenage Dream” (Capitol) hung in at No. 4 behind a 59,000-unit week (down 33%). The previous week’s No. 1 entry, Disturbed’s “Asylum” (Warner Bros.), fell to No. 5, moving 57,000 and plunging 68%.

Metal unit Stone Sour’s third release “Audio Secrecy” (Roadrunner) bowed at No. 6, shifting 46,000. Iowa headbangers’ last release, 2006’s “Come What(ever) May,” debuted at No. 4 with an 80,000-unit week.

Moody New York combo Interpol’s self-titled fourth album, which sees them returning to original home Matador Records, entered at No. 7 with a 38,000-unit debut week. Group’s last effort, 2007’s “Our Love to Admire,” peaked at No. 4.

Another performer likely to see an MTV-induced boost next week, teen dream Justin Bieber, hung on at No. 8, as “My World 2.0” (Island) moved 35,000 (a 14% uptick).

Florida alt-rock unit Anberlin’s fifth studio album and second Universal Republic release “Dark Is the Way, Light Is a Place,” arrived at No. 9, matching the peak of its 2008 release “New Surrender.” Set sold 31,000.

Soundtrack for the Disney Channel pic “Camp Rock 2: The Final Jam” (Disney Buena Vista) dipped one notch to No. 10. Collection featuring the Jonas Brothers and Demi Lovato tracked fewer than 100 units less than the Anberlin collection, showing an 11% gain.

Beyond the top 10, U.K. folk-rock unit Mumford & Sons benefitted from the week’s lull: Group’s “Sigh No More” (Glassnote) was lofted 10 positions to No. 16 on flat sales of 16,000.

Distaff Irish act Celtic Thunder posted the first Yuletide album of the year with “Christmas” (Decca), which moved in at No. 27 with 12,000 sold.

The seemingly eternal rockabilly pioneer Jerry Lee Lewis’ “Mean Old Man” (Verve Forecast) debuted at No. 30; star-studded entry by the pumpin’ piano man jumped out of the box with 11,000 units.

Numbers should improve next week with arrival of much-anticipated new releases by Linkin Park, Trey Songz, Weezer, Robert Plant and Jamey Johnson and post-MTV boosts for big winner Lady Gaga and performers Drake, Usher and Florence & the Machine.
