Mighty Sparrow
Calypso music enjoyed a brief period of popularity in other parts in the world during the 1950s. Trinidadian expatriate Lord Kitchener had helped popularize calypso in England, and Sparrow also found some success there. In the United States, interest in calypso was sparked largely by Harry Belafonte's 1956 album "Calypso", the first LP to sell over one million copies. In January 1958, Sparrow, along with longtime rival Lord Melody, travelled to New York City seeking access to the American music audience. Sparrow had already been recording with Balisier and Cook Records, and with Belafonte's help he also began to record for RCA Victor. He did not achieve the success he had hoped for; he said in a 2001 interview, "When nothing happened for me, I went back to England and continued on with my career."
American rock
In 1968 Gram Parsons recorded "Safe at Home" with the International Submarine Band, arguably the first true country-rock album. Later that year he joined the Byrds for "Sweetheart of the Rodeo" (1968), generally considered one of the most influential recordings in the genre. The Byrds continued in the same vein, but Parsons left to be joined by another ex-Byrds member Chris Hillman in forming The Flying Burrito Brothers who helped establish the respectability and parameters of the genre, before Parsons departed to pursue a solo career. Country rock was particularly popular in the Californian music scene, where it was adopted by bands including Hearts and Flowers, Poco and New Riders of the Purple Sage, the Beau Brummels and the Nitty Gritty Dirt Band. Some performers also enjoyed a renaissance by adopting country sounds, including: the Everly Brothers; one-time teen idol Rick Nelson who became the frontman for the Stone Canyon Band; former Monkee Mike Nesmith who formed the First National Band; and Neil Young. The Dillards were, unusually, a country act, who moved towards rock music. The greatest commercial success for country rock came in the 1970s, with artist including the Doobie Brothers, Emmylou Harris, Linda Ronstadt and the Eagles (made up of members of the Burritos, Poco and Stone Canyon Band), who emerged as one of the most successful rock acts of all time, producing albums that included "Hotel California" (1976).
