In the early 1960s, he auditioned for The Sunliners but did not get the part, however one year later they brought him into the group. The Sunliners changed their name to
Rare Earth in 1968 and became the first act that was signed to one of
Motown's new sub-labels dedicated to just white acts; after the band joked that the nameless label should be also called "Rare Earth", the label agreed. From 1968 to 1983, Rivera was the lead singer and drummer for Rare Earth, whose biggest hits were covers of other Motown and soul records including "
Get Ready" (US #4, CAN #1), "
(I Know) I'm Losing You" (US #7), and "
What'd I Say" (US #61), but are best known for their original song, "
I Just Want to Celebrate" (US #7). Rivera left in 1983 after arguements with saxophonist
Gil Bridges. Rivera tours as a solo artist and in 1992, formed
The Classic Rock All-Stars with a core lineup of
Jerry Corbetta of
Sugarloaf,
Mike Pinera of
Blues Image and Dennis Noda of
Cannibal & the Headhunters. In 2016, Rivera's vocals were used in the
Kanye West song "
Fade". From 2019 to 2021, Rivera hosted his own podcast in which he spoke about his life and career. He performed two concerts in 2023 with his own orchestra, R&B Celebrate Symphony. == Personal life ==
