>Silk Degrees may have been the name of singer Boz Scaggs's 1976 breakthrough album, but maybe it also indicates the Fahrenheit level of slyness in Scaggs's sleek mix of R&B, blues, soul, jazz, and sophisticated pop. These days Scaggs is in prime form and having a blast as a veteran pop savant. He's added jazz standards to his repertoire over the last few years. His smart phrasing and Gil Goldstein's agile arrangements made the Great American Songbook tunes on 2008's Speak Low glisten. Last summer, Scaggs toured with Donald Fagen and Michael McDonald as the Dukes of September. And now, Scaggs is on the road running through his greatest hits mixed up with standards plus maybe the odd R&B nugget. Meanwhile, he's got two new albums in the works: another collection of standards and an all-originals disc, his first in well over a decade.
