Efficacy is one of my favorite albums. To start off, "Noname" and "Quantum" make you feel like you're flying through space watching the giant space monsters from DoG's album covers destroy planets, then "The Pretty Song" and "Skyride" are like the eerie calm after the storm, leaving you to wonder "did that just happen?" at the end of the album. Delusions of Grandeur have found that perfect balance of heavy and beauty. Quantum is one of my favorite songs, if not my favorite. 1:21 is perfect.
Favorite track: Quantam.
