María Isabel Anita Carmen de Jesús Vargas Lizano, known professionally as Chavela Vargas, was a Costa Rican-born singer, songwriter and actress, naturalized Mexican citizen. She gained widespread recognition for her distinctive interpretations of Mexican rancheras. However, her impact extends beyond this genre, encompassing various styles within popular Latin American music.

Violeta del Carmen Parra Sandoval was a Chilean composer, singer-songwriter, folklorist, ethnomusicologist and visual artist. She pioneered the Nueva Canción Chilena, a renewal and a reinvention of Chilean folk music that would extend its sphere of influence outside Chile.

Álvaro Lafuente Calvo, known professionally as Guitarricadelafuente, is a Spanish singer-songwriter, guitarist and actor based in Barcelona.

Charlie Hunter is an American guitarist, composer, producer and bandleader. First coming to prominence in the early 1990s, Hunter plays custom-made seven - and eight-string guitars on which he simultaneously plays bass lines, chords, and melodies. Critic Sean Westergaard described Hunter's technique as "mind-boggling...he's an agile improviser with an ear for great tone, and always has excellent players alongside him in order to make great music, not to show off." Hunter's technique is rooted in the styles of jazz guitarists Joe Pass and Tuck Andress, two of his biggest influences, who blended bass notes with melody in a way that created the illusion of two guitars.
