“I was noticing I was having a hard time playing a simple thing. ‘Why am I having a problem playing this?’ I didn't know yet”: Phil Collins’ go-to guitarist, Daryl Stuermer, reveals his Parkinson’s diagnosis – and shares how it has impacted his playing

Daryl Stuermer from Genesis performs at U Arena on March 17, 2022 in Nanterre, France.

Daryl Stuermer may best be known as the six-stringer behind Phil Collins' biggest hits, with his electric guitar chops on full display on iconic tracks such as Sussudio, In The Air Tonight, Easy Lover, and One More Night.

Aside from being Collins' right-hand man, Stuermer also had (as he aptly puts it) a “permanent part-time stint” as lead guitarist with Genesis, from late 1977 onward. Now, in a frank conversation with Vertex Effects, the guitarist has shared his Parkinson's diagnosis and revealed how the condition has impacted his playing.
