Signposts and Instruments opens Arbouretum’s Rites of Uncovering with a low rumble-the smooth, deep growl of a bass and fingers gently fretting a guitar. It’s a subtle start, but the song’s lurch comes off decidedly physical. Immediately, we realize that Baltimore’s Arbouretum creates songs to be felt. Then singer Dave Heumann’s round, whole-milk voice cuts through the weighty semi-silence, doing a perfect backstroke through the song’s guts. Borrowing from Will Oldham, Codeine, and Black Sabbath along the way, Heumann and his bandmates have created what can only be called the best doom-folk record of all time.
