Aerosmith guitarist Joe Perry has credited Peter Green's Fleetwood Mac as the blueprint for his own band, praising the group's collective, jam-based dynamic over a conventional frontman-led setup. Perry's remarks, made to Guitar World in 2020 following Green's death, trace a musical lineage from The Beatles' influence on his teenage years through to his discovery of Green, whom he singled out as an underappreciated songwriting talent overshadowed by Santana's hit cover of "Black Magic Woman".

Perry highlighted Green's brief stint in John Mayall's Bluesbreakers, which he joined in 1966 as Eric Clapton's replacement before leaving after one album to form Fleetwood Mac in 1967 with fellow former Bluesbreakers members Mick Fleetwood and John McVie. He pointed to 1969's "Then Play On" as the album where Green fully combined his blues technique with his songwriting, though it proved to be his last with the band before he departed in May 1970, reportedly just as Fleetwood Mac stood on the cusp of arena-level success comparable to Led Zeppelin and The Who.
