Mark Volman and Howard Kaylan are best known as the front men for ’60s folk-rock group The Turtles (“Happy Together,” “Elenore,” “You Showed Me”). After the band broke up, they joined Frank Zappa’s Mothers of Invention using the noms de plume Phlorescent Leech and Eddie. Flo and Eddie, as they’d later be known, went on to record backing vocals on 100+ recordings with the likes of Springsteen, the Ramones, T-Rex, Ray Manzarek, and other top acts.

The pair learned much over their careers in the music biz and became extremely savvy about the music business — but not without having suffered their fair share of pain, which brings the following quote to mind:

“The music business is a cruel and shallow money trench, a long plastic hallway where thieves and pimps run free, and good men die like dogs. There’s also a negative side.”  —Hunter S. Thompson
