Orchestral indie rock band the Arcade Fire notched its first No. 1 album last week, as “The Suburbs” fended off Eminem’s still-potent “Recovery” to conquer the top of the U.S. album chart.

The Montreal group’s third studio album, released by North Carolina indie Merge Records, sold 156,000 copies its first week, according to Nielsen SoundScan figures for the week ended Sunday. That was enough to hold back “Recovery,” which held on at No. 2 with 152,000 sold.

The Arcade Fire’s last album, “Neon Bible,” entered the chart at No. 2 in 2007. A powerful confluence of events lofted “The Suburbs” to the zenith, including a much-trumpeted webcast directed by Terry Gilliam, a headlining appearance at Lollapalooza and Amazon MP3 pricing of $3.99.

Rapper Eminem’s “Recovery” declined just 4% in its seventh week on the chart. Title is closing in on the 2 million mark.

Previous week’s No. 1 album, “Nightmare,” from Southern California metallurgists Avenged Sevenfold, toppled to No. 3 behind a 72% decline, shifting 45,000.

Texas rapper Bun B’s “Trill O.G.” (Rap-a-Lot) arrived at No. 4, busting in with 41,000 units sold. Set is former UGK’s member’s third solo release.

Miami rap power Rick Ross’ “Teflon Don” (Def Jam) slipped two rungs to No. 5, charting a 37% drop with 39,000 sold.

Fresh from a triumphant appearance at Lollapalooza in Chicago, Lady Gaga added another chart feather to her well-decorated cap, as her “The Remix” (Interscope) entered at No. 6 with a 39,000-unit debut week. Set comprises new mixes of Gaga hits by Richard Vission, Stuart Price, Starsmith and other top DJs.

Showing minor movement and hanging on in the top 10 were Justin Bieber’s “My World 2.0” (No. 7, 37,000 sold, off 2%), Drake’s “Thank Me Later” (No. 8, 31,000, down 9%) and Lady Antebellum’s “Need You Now” (No. 9, 29,000, up 4%).

Wrapping the top 10 was Buckcherry’s new “All Night Long” (Eleven Seven), which rocketed in at No. 10 on a 28,000-unit launch. Set was two slots off the No. 8 debut of L.A. hard rock unit’s last album, 2008’s “Black Butterfly.”

Summer hitmaker Mike Posner’s major league debut, a country six-pack from Blake Shelton and the Jonas Brothers-Demi Lovato soundtrack “Camp Rock 2” are all poised for big chart entries this week.
