Philip Kenneth Collen (born 8 December 1957) is an English guitarist and singer‑songwriter best known for his long service as a lead guitarist in the rock band Def Leppard. Born and raised in London, Collen became a full member of the group in 1982 during the recording of the Pyromania album, replacing Pete Willis. Since then he has been a central figure in the band’s evolution from raw hard rock toward the polished, multi‑layered sound that brought them international success.

Career and role in Def Leppard

Collen joined the group at a pivotal moment while the band was working on what would become a breakthrough record. He contributed to recording sessions, live performances and songwriting across subsequent albums, including the commercially and critically significant releases that followed. His interplay with fellow guitarist Steve Clark (and later with Vivian Campbell) produced the twin‑lead guitar harmonies and tightly arranged parts that became a hallmark of the band’s sound. Collen has played on multiple major studio albums and on worldwide tours that established Def Leppard as a leading act in the 1980s and beyond.

Playing style and equipment

Collen’s playing is noted for its combination of melodic phrasing, precise technique and high‑energy solos suited to arena rock. He blends single‑note runs, double‑stops and layered rhythm parts to create full guitar textures in studio recordings and live shows. Over his career he has used a variety of electric guitars, effects and high‑gain amplifiers, and has collaborated with instrument makers on signature models. His approach emphasizes clarity, timing and complementing vocal melodies rather than purely virtuosic display.

Side projects, collaborations and influences

Outside his main band activity, Collen has been involved in other musical projects and collaborations, working with musicians across rock and pop contexts. He was a member of supergroup and side projects that explored a rawer, garage‑influenced sound as a contrast to his work in the stadium setting. Those ventures show his interest in songcraft and in keeping a variety of musical outlets active alongside his role in Def Leppard.

Personal background and public profile

Born in London, Collen’s musical upbringing included exposure to the British rock tradition and the emerging hard rock scenes of the 1970s. He has been public about maintaining physical fitness and a lifestyle that supports demanding touring schedules. Collen’s public persona combines the showmanship of an arena performer with an interest in technical aspects of guitar tone and live sound.

Legacy and notable recordings

Collen is widely recognized among rock guitarists for his work creating durable, radio‑friendly arrangements that still sustain interest in live performance. Key records that feature his playing include the albums completed after he joined the band and later major releases that cemented the group’s international reputation.
