Ian MacKaye
Aside from fronting three of the biggest punk bands in musical history (Minor Threat, Embrace & Fugazi), Ian MacKaye set an achievement of personal integrity that few entrepreneurial musicians have even come close to touching. While other musicians elect to just focus on their job in the studio, MacKaye's intensely self-righteous business ethic extended to pretty much every aspect of his touring act as well:
No self promotion.
No merch.
No roadies, no drivers, no managers, no hotel rooms.
$5 shows.
From the early '80s onwards, MacKaye's D.C. label, Dischord Records, was a proprietary force in the burgeoning post-hardcore scene; plenty of the roster have gone onto punk immortality: Nation of Ulysses, Rites of Spring, Dag Nasty, Lungfish among others. None of their LPs were ever offered for over $10.
