Career

Following his guitar performance at the school's talent show, Heafy was asked to try out for Trivium by the band's original singer Brad Lewter. Originally, he was accepted as lead guitarist, despite being only 12 years old (other members were 15-16 at that time). Lewter, however, quit the band in less than a month due to creative differences over the band's future musical direction. The drummer
Travis Smith persuaded Heafy to do vocals, even though Heafy himself was unsure of his singing voice at that time. The band started looking for an external singer to fill in the position but had trouble finding a suitable candidate. Eventually, Heafy agreed to become a full-time lead singer for Trivium also keeping the position of lead guitarist for the band. He taught himself

, especially doing so during the band's early years. However, he admitted using the techniques incorrectly most of his career, which ultimately caused severe damage to his vocal chords in the years leading up to the band's performance at

Ron Anderson, following advice from

. In 2016, Heafy returned to performing unclean vocals live with the same frequency as he did before his injury, citing Anderson's lessons as a source of help and improvement. He claims that the new technique is actually easier than normal talking.

In Waves'', was released with a 'greater emphasis on songs rather than skill,' with the album featuring the full range of Heafy's vocal talents with some songs being entirely composed of screaming, others with no screaming at all, and many songs that fused the two as with previous records.
In Trivium, Heafy sometimes shares lead guitar duties with
