Lawyer Debra Grassgreen of Pachulski, Stang, Ziehl, Young & Jones in West Los Angeles is singing the blues — but not in the traditional sense.

Grassgreen is upbeat about her role in the upcoming Jan. 18 auction at U.S. Bankruptcy Court in Los Angeles, in which one of the great rhythm and blues music catalogues is going on the block so Ronald Isley, a member of the Isley Brothers, can pay his back taxes.
