Los Jaivas (1963 - ) is a well-known Chilean folk/progressive rock band. The Parra brothers (Gabriel, drums Claudio, piano, and Eduardo, electric piano) met Mario Mutis (bass) and Eduardo "Gato" Alquinta (guitars and lead vocals) in their childhood and started to play music for fun. They became prominent in Viña del Mar, playing at many gigs with a bossa-nova/bolero style. The former name of the band was High & Bass. However, most of their fans believed they were called "Jaibas" (crabs). After a while they decide to correct their name and definitely change it to Los Jaivas.
