The Grammy Awards may not have the sales driving power that they once had, but they can still provide a pop for the winners and performers.

Merchants say that album of the year winner "Raising Sand" by Robert Plant & Alison Krauss appears to be the main sales beneficiary among the Grammy recipients, while best new artist winner Adele's album, "19," is enjoying the second-largest sales jump.

"But it's not like a couple of years ago when Norah Jones won and her album ["Come Away With Me"] exploded," says Rob Perkins, president of the Marietta, Ga.-based retail chain Value Music. "The Grammy show is not near what it used to mean for sales, but what is nowadays? It may be that there are too many awards shows or it may be the economy or the malaise the music industry is in."

At Hastings Entertainment in Amarillo, Texas, senior VP of merchandising Alan Van Ongevalle reports that by midweek, "Raising Sand" was up more than 600% from the week before, while "19" was up 225% at the 154-unit chain.

Newbury Comics head of purchases Carl Mello says that in the two days following the Feb. 8 Grammy telecast, "Raising Sand" had sold seven times more copies than it did in the entire previous week, while Adele was up 2.5 times. With a full week of sales, he expects those multiples to grow.

At Trans World Entertainment, director of merchandising operations and new media Ish Cuebas says the Plant/Krauss album is seeing a "15-times lift" over the previous week's sales.
