We saw Jake Armerding live two weeks ago, and I bought his CD. Boston-scene singer-songwriter multi-instrumentalist. He carries a "folk" categorization, but he's got a more Allison Krause sound to me. Or Western Swing, or Nickel Creek.
If I tell you some guy is a brilliant lyricist and then quote those lyrics in print, it always looks lame. Lyrics occur in musical context, and without that skeleton, they just lie around like flesh on the floor. But I can give you some hint by telling you that his "Ithaca" is about Odysseus, not New York, and the happy "Little boy Blue" is subtitled North of North Dakota.
