When a band loses its lead singer, it can be difficult for the remaining members to continue creating the same sound. Many music fans, casual ones in particular, identify an artist or band by the dominant singing voice, and future iterations with a different lineup can struggle to retain their audience. When the Louisville hardcore band Breather Resist lost its frontman in late 2005, the remaining members stayed together, but took his departure as a chance to drastically change their sound. Guitarist Evan Patterson and bassist Nick Thieneman assumed vocal duties, and the remaining trio, newly dubbed Young Widows, abandoned the chugging hardcore of its previous records for a heavy, hazy strain of noise-rock.
"Future Heart" is more straightforward than the rest of the songs on In and Out of Youth and Lightness, Young Widows' third full-length album. While the rest of the record is filled with slow-building hypnotic drones, "Future Heart" is pounding, sludgy and hot-blooded. Although it may differ in terms of pace, the song still works, thanks to guitars fed through scathing distortion and towering walls of reverb, a combination Patterson uses to pull a surprisingly wide variety of sounds from his instrument. After a few bars of what sounds like a cavernous room filled with a hundred different bells ringing at once, snarling guitar riffs plow their way through until the song's end.
