The Downtown Mountain Boys, one of the Pacific Northwest’s most polished bluegrass bands, is all about spirited three-part harmonies, virtuosic instrumentation, a deep-rooted admiration for old-time and traditional American music. These veteran bluegrassers are some of Seattle’s best pickers, teachers and session musicians. From the barn-burning opening song Back in the Black to title track Big Darlin’ The Downtown Mountain Boys latest effort is one solid bluegrass record.
