Keith Judelman (upright bass and vocals) was born and raised in Seattle, where he began studying music at a young age. Originally pursuing a career in jazz, he met some Cuban jazz musicians at a festival in 2000 and was instantly captivated by what they brought to the music. Intrigued and inspired, he travelled to the Caribbean to learn more about the African roots of Salsa and Son, and has been in love with this music ever since. In addition to the 'Sones, he composes and plays with Picoso.
David Trejo (acoustic guitar and vocals) was born and raised in Mexico City. He studied guitar at Escuela de Iniciacion Artistica, D.F., and Escuela de Musica, Universidad De Guadalajara. From 1977-79, David toured Mexico playing guitar and charango with the folkloric dance troupe Tenayo. David arrived in Seattle in the 1980's and founded two Mexican ensembles - Los Huitlacoches and Los Nopalitos. Having been enamored with Cuban music since his youth, he traveled to Cuba several times to study and play music. David co-founded the Seattle based Cuban Son groups Son de Cinco a Siete and Los Nietos del Son.
