Patrick Dethlefs plays January 12 at the Walnut Room

It’s fairly obvious that Patrick Dethlefs — a transplant from Tacoma, Washington, who now makes his home in Kittredge, Colorado, of all places — is no stranger to the kind of focused introspection that yields the mature songwriting style he has cultivated at a relatively young age. Folk? Americana? Sure, but when someone is clearly coming from a deep place in his psyche and soul, it shines through in his writing, as Dethlefs deftly proves. This notion is especially evident when he teams up with The Eye and the Arrow, which includes members of Paper Bird. On Thursday, January 12, at the Walnut Room, the two acts will release a collaborative album that seems at times to channel Jorma Kaukonen on “Embryonic Journey.” But mostly this partnership has produced a soothing amalgam of the earthy and the sublime.
