Old hands Willie Nelson, B.B. King and Eric Clapton continue to dominate the blues and Americana charts this week.

Nelson's Me and the Drummer tops the Gavin Americana radio-play survey for the second straight week, and King and Clapton's Riding With the King extends its run at #1 on the Billboard Top Blues Albums chart to nine weeks.

Riding With the King also rides high on the Billboard 200 pop albums chart, remaining at #12.

The young 'uns are still being heard from, though. One of the youngest, Shannon Curfman, the blues guitarist who turned 15 on July 31, shoots to #6 from #10 on the blues chart with her 1999 debut album, Loud Guitars, Big Suspicions. Curfman is spending her summer vacation on a tour that wraps Sept. 17 at Farm Aid 2000 in Bristow, Va.

Allison Moorer, the younger sister of Shelby Lynne (born Shelby Lynne Moorer), leaps to #8 from #16 on the Americana radio-airplay survey with her sophomore effort, The Hardest Part. The album, due to hit stores here Sept. 26 — it's already spent six weeks on the UK country chart — is being introduced by the single "Send Me an Angel" (RealAudio excerpt).

The most compelling part of The Hardest Part is its "buried" final track, "Cold Ground" (RealAudio excerpt), in which Moorer deals for the first time with the circumstances of her father killing her mother, then taking his own life.

Transatlantic Sessions also makes a strong move this week on the Americana chart, jumping to #5 from #11. An all-star cast, including Ricky Skaggs, Nanci Griffith and Rosanne Cash, takes turns on this compilation, released on Skaggs' label, Ceili.

Rounding out the top 10 on the Americana chart are: Steve Earle, Transcendental Blues, at #2; Joe Ely, Live at Antone's, at #3; Max Stalling, Wide Afternoon, at #5; Tish Hinojosa, Sign of Truth, at #6; Little Feat, Chinese Work Songs, at #7; Pat Green, whose Carry On falls to #9 from #5; and Dwight Yoakam, dwightyoakamacoustic.net, at #10.

The rest of the Top Blues Albums top 10 is: Johnnie Taylor, Gotta Get the Groove Back, at #2; Kenny Wayne Shepherd Band, Live On, at #3; Jonny Lang, Wander This World, at #4, switching places with #5 Blues at Sunrise by Stevie Ray Vaughan and Double Trouble, whose The Real Deal: Greatest Hits Vol. 2 is at #7; B.B. King, Best of B.B. King: The Millennium Collection, at #8; Etta James, Best of Etta James, at #9; and Mel Waiters, Material Things, at #10.
