Named after the idea of learning from the established geniuses of blues, Adelaide’s The Masters Apprentices debuted with 1966’s “Undecided,” a distorted garage romp that showed off Jim Keays’ snide, roughshod vocals and the players’ past forays into surf rock. The next year’s “Living in a Child’s Dream” proved softer and more psychedelic, cracking the Top 10. By the close of the decade, the band was leaning into that schoolyard whimsy with “Linda, Linda” while pairing throwback vocal harmonies with Doug Ford’s big, smoky guitar solos on “5:10 Man.” Their hard-rocking 1970 single “Turn Up Your Radio” became the biggest chart hit of their career and spawned a collaborative version with spiritual heirs Hoodoo Gurus in 1995. Combining 12-string acoustic guitar with brash electric riffs, 1972’s “Love Is” pointed toward more progressive terrain, but the band had parted ways by year’s end. A reunion the following decade yielded a 1988 album and the single “Birth of the Beat,” which lyrically revisited the Masters’ early days while sonically paying tribute to current hard rock. Keays died in 2014, but as he sings on that song: “Rock ’n’ roll music will never fade away.”
