With Gillian Welch’s ethereal voice alongside Dave Rawlings’ masterfully intricate guitar playing, the musical partners have been a singular treasure in Americana music for more than 15 years.
Most of their collaborations have been released as Welch’s critically acclaimed solo work, where Rawlings primarily harmonizes. In the lesser-known Dave Rawlings Machine, the two essentially flip the perspective, sending Rawlings up front, with Welch on harmony duty.
Their complementary voices intertwine in unexpected ways, often adding another shade of darkness to their Gothic brand of old-time folk. In all, the Machine version of the two comes across as slightly more experimental than Welch-branded material, and in no rush at all.
On the latest album, “Nashville Obsolete,” the follow-up to the 2009 debut “A Friend of a Friend,” they stretch out what begins as a simple song for more than five minutes, allowing the listener to sop up all the intricacies of their lyrics, vocal layers and strings work as the complexity builds.
The band is beefed up by Punch Brothers bassist Paul Kowert, former Old Crow guitarist Willie Watson, violinist Brittany Haas and mandolinist Jordan Tice. In support of the new work, they will make their way to the Charleston Music Hall on a rare spring tour to the Southeast.
The local show also offers the tour’s only co-headlining slot with the Punch Brothers, an acoustic quintet led by mandolin virtuoso Chris Thile.
When: 8 p.m. Friday
Where: 37 John St.
