Two songs conjure up the spirit of a graveyard especially well to me. "In Memory Of Elizabeth Reed" by The Allman Brothers Band has always been one of the strongest album rock instrumentals, in my opinion. Inspired by an actual tombstone, the organ and guitar-based number establishes its haunting vibe right from the first note and never relinquishes it. Not just any band can pull off such a feat for seven minutes.
Vocally, Hem's "Walking Past The Graveyard, Not Breathing" pulls off the impressive trick of sounding jaunty yet contemplative. Thoughtful lyrics acknowledge the losses we have faced and will face in life while giving thanks for still having the breath to tell those we've lost how much we miss them.
Both songs fit the Halloween bill well, with depth to spare.
