Kevin William Klein is a singer-songwriter and producer, better known as the frontman of Massachusetts-based alt-rock band, Valleyheart.

Since 2009, Klein was the clean vocalist and lead guitarist for the hardcore Christian band, Exiting The Fall, which released three EPs Beyond The Experience, Parables and Bloodline; and an album called Windchaser. The band broke up in 2015.

That’s when Kevin released his first solo EP, Current Fears. The following year, he formed Valleyheart with some of the members from Exiting The Fall, playing guitar and being the lead vocalist. With them, he released an EP called Nowadays, which was later remastered after the band got signed by the label Rise Records.

In 2018, Kevin released his next solo work, Matter Of Time, a folk EP that contains songs that wouldn’t lyrically fit Valleyheart. But by the end of that year, the band put out their first full-length album, Everyone I’ve Ever Loved, which deals with Kevin’s deconstruction and construction of belief.

After a few label changes, Valleyheart and Kevin ended up in Tooth & Nail Records, where the band released their second full-length Heal My Head in 2022, and Kevin’s Random Spaces EP in 2023.
