[4][5] According to Graham Hartmann of Loudwire, "Greenway’s primordial swamp-thing barking is one of extreme metal’s most distinct and imposing voices.

The albums that followed this, including Utopia Banished, Fear, Emptiness, Despair and Diatribes, saw the band delve further into the aforementioned style whilst also incorporating elements of groove metal.

[8] Greenway has remained with Napalm Death since 1997, have since released a number of critically acclaimed albums,[citation needed] and became as the band's longest-serving lead vocalist.

He joined Dream Theater on stage at Ronnie Scott's Jazz Club and performed vocals on Metallica's "Damage, Inc." live.

[13][14] Greenway is recognisable for his strong Birmingham accent and for his distinctive gruff vocal style which many feel has become synonymous with Napalm Death.
