カントリーロック
In 1967 Guilbeau formed The Reasons (aka "Nashville West," actually the name of a club they played at in El Monte, CA), a short-lived country rock group with multi-instrumentalist Gene Parsons, who had played with Guilbeau in a band called the Castaways years earlier, guitarist Clarence White, formerly of the Kentucky Colonels, and Wayne Moore on bass. Along with bands such as the Byrds, Dillard &amp; Clark and the International Submarine Band, Nashville West was one of the first country rock bands. Country rock notables such as Gram Parsons and future Flying Burrito Brother Sneaky Pete Kleinow would sit in with the group. It also provided backing for other groups, such as the Gosdin Brothers and others on Gary Paxton's Bakersfield International record label. The Reasons came to an end in 1968 when Gram Parsons abruptly left the Byrds and the group asked Clarence White (and, shortly thereafter, Reasons drummer Gene Parsons—no relation) to replace him.
