Just certified gold, with sales in excess of 500,000 copies in only four weeks of release, B.B. King and Eric Clapton remain at #1 on the Billboard Top Blues Albums chart with Riding With the King.

The album also holds its own on the Billboard 200 pop albums chart, remaining at #10. And coming along for the ride is the guitarist's Best of B.B. King: The Millennium Collection, which jumps to #9 from #13.

Veteran singer Etta James also makes a strong move, as her Best of Etta James (MCA) advances to #10 from #14.

Moving up briskly on the Gavin Americana chart is Joe Ely, whose Austin-powered Live at Antone's jumps to #2 from #4. But despite strong concert versions of such Ely staples as "Nacho Mama" (RealAudio excerpt) and "All Just To Get to You" (RealAudio excerpt), Live at Antone's can't dislodge #1 Steve Earle's Transcendental Blues, which also remains at #20 on the Billboard Top Country Albums chart.

Rounding out the Americana chart are Nickel Creek's Nickel Creek at #3; Pat Green's Carry On, moving up to #4 from #6; Todd Snider's Happy To Be Here at #5; Neil Young's Silver & Gold at #6; Willie Nelson & the Offenders' Me and the Drummer jumping to #7 from #10; Stacey Earle's Dancin' With Them That Brung Me at #8; Tim O'Brien & Darrell Scott's Real Time at #9; and Big House's Woodstock Nation at #10.

The rest of the top 10 on the blues chart: Johnnie Taylor's Gotta Get the Groove Back at #2; Stevie Ray Vaughan and Double Trouble's Blues at Sunrise at #3; Kenny Wayne Shepherd Band's Live On at #4; Jonny Lang's Wander This World at #5; Stevie Ray Vaughan and Double Trouble's The Real Deal: Greatest Hits Vol. 2 at #6; Indigenous' Circle at #7; and Shannon Curfman's Loud Guitars, Big Suspicions at #8.
