The Kingston Trio
The Kingston Trio is an American folk group. They helped launch the folk revival of the 1960s and continued to thrive despite the emergence of rock and roll.
The Kingston Trio was formed in 1957 in the Palo Alto, California, area by Bob Shane, Nick Reynolds, and Dave Guard, who were just out of college. Greatly influenced by The Weavers, the calypso sounds of Harry Belafonte, and other semi-popular folk artists such as the Gateway Singers and the Tarriers, they were discovered playing at a college club called the Cracked Pot by Frank Werber, a local publicist then working at the Hungry i. He became their manager, and secured them a one-shot deal with Capitol Records.
Their first hit was a catchy rendition of an old-time folk song, "Tom Dooley," which went gold in 1958. It was so popular that it entered popular culture as a catchphrase: Ella Fitzgerald, for example, parodies it during her recorded version of "Rudolph the Red-Nosed Reindeer." It won them the first Grammy award for Best Country & Western Performance in 1959. The next year, they won the first Grammy Award for Best Ethnic or Traditional Folk Recording category for the album The Kingston Trio at Large.
At one point in the early 1960s The Kingston Trio had four albums at the same time among the Top 10 selling albums, a record unmatched for nearly 40 years. In spite of this, they had a relatively small number of hit singles.
The group's music was simple and accessible, with much use of tight vocal harmony, signature riffs (often played on the banjo), and repetitive choruses. Capitol producer Voyle Gilmore enhanced their vocal sound to great effect with reverb and the relatively new process of doubletracking, in which the performers sang along with their own pre-recorded part to produce a stronger sound than with a single voice, in part due to a natural time gap of a fraction of a second between the original recording and the overdubbed part. At first pairs of tape recorders were used, then later multitrack recording machines, to produce the effect...
