David Haerle’s “Do You Know Surrender?” is an effort that immediately adopts interesting time signatures and additional instruments beyond the traditional guitar/drum dynamics. A waltz-like set of strings immediately varies things, while Haerle’s vocals brings up hints of prog-rock. There is considerable charisma to each lyric in Do you Know Surrender?, while the middle bridge is perhaps the song’s high-water mark. The dynamic between both guitars, bass, drums, and strings is impressive; one will have to play the single multiple times before hearing each and every nuance that is contained within. Quite possibly Haerle’s best yet.
