The origins of Los Jaivas lie in the family nucleus formed by the brothers Eduardo, Claudio and Gabriel Parra, of Vina del Mar. Together with your friends and colleagues from College of the Liceo Guillermo Rivera Cotapos, street mountain steps from the Quinta Vergara in Vinadel sea, Eduardo Gato Alquinta, Mario Mutis and Felipe Trujillo, begin to discover the music as a way of expressing your creativity and permanent concern. Thus, as of August 15, 1963, under the name of The High & Bass, which referred to the differences in height between the Parra brothers, Jack and Mario, made its first presentation at the Teatro Municipal of Vinadel sea, performing, among others, dreams, Luis Dimas. The presentation is disastrous and the public strongly disapproves them. During the next six years, and with its stable formation (Eduardo on piano, Claudio on accordion, Gabriel on drums, Jack on guitar, Mario on bass and danipercusiones and Philip on guitar electric), the band developed its proposal music at parties and social gatherings vinamarino, performing mainly tropical music, cha cha cha, bossa nova and boleros, with good results.
After these years of learning, and test the Group strongly questioned his work, and influenced by the University reform and the ideal americanists, decides to modify its estilomusical, to move from mere interpreters to creators and leave step to full musical improvisation and avant-garde. Between 1969 and 1971, and his already Spanish name to Los Jaivas, the concerts of the group are transformed into absolute improvisations, which lasted long hours, without scripts or prepared schemes, and every musical instrument generating own atmospheres, even with the help of the audience, many of these improvisations have hatched publicads recently, observing the nature of them. Improvisation leads them to the valuation of the Latin American musical roots and the exploration of sounds of ancient instruments, and also instruments or rather non-traditional items to make music, like straws in glasses of water, things falling etc.
