The wood darkens over time, rich with age, filled with sound. The music of these two acoustic roots masters, singer, guitar, multi-instrumentalist Eli West and Norwegian hardanger fiddler Olav Mjelva holds the same rich tones, and, like old wood, has become burnished with use. Their new album, Hand to Play, explores the old sounds of Scandinavia and America, and though both of these artists are renowned in their own fields, there's a sense of restraint in what they're doing here. It's a freeing restraint though, the sense that these two artists are holding back in order to play more closely. Their ornaments and cross rhythms interlock, and they trade the lead on instrumentals back and forth. This kind of careful precision doesn't come easy, and both West and Mjelva clearly delight in this kind of powerful musicianship.
