Theresia Bothe was born in Canada to an Irish mother and German father, and grew up in Mexico. Early on she developed a passion for singing, particularly popular and traditional music. She began formal voice studies in Mexico City, and continued in London and at the Schola Cantorum Basiliensis in Switzerland, specializing in music of earlier periods. She has performed frequently in Mexico and throughout Europe as a soloist, in ensembles or accompanying herself with guitar or lute. She enjoys performing all sorts of styles of music, from ancient Greek, through medieval, baroque, classical, opera, contemporary to folk, jazz or free improvisation in formal and informal situations. Theresia Bothe now lives in Switzerland, where she also teaches voice and directs choirs and a-capella vocal ensembles. In addition to teaching and performing, she has founded M-CC (Music - a Chance for Change), an organization which intends to help integrate music into the work of human rights organizations and related independent projects.

Peter Croton grew up in the USA and presently lives in Switzerland. As a child of six he began performing as a folk guitarist and singer, and later also played guitar in various jazz ensembles. Peter's musical roots in folk and jazz were supplemented by studies of the lute and classical guitar at the Oberlin Conservatory of Music and at the Schola Cantorum Basiliensis in Switzerland. In 1984 he won first prize at the "Erwin Bodky" competition for Early Music in Boston, and has also won prizes at the international lute competition "Guitar '84" in Toronto and at the international competition "Concert Artists' Guild" in New York City. He is an active performer in Europe and the USA as a soloist and chamber musician, and his musical spectrum reaches from early music to folk, jazz standards, and popular idioms. Peter teaches lute and historical performance practice at the Schola Cantorum Basiliensis and the Conservatories of Music in Basel and Bern. Since 1984 he has been involved in numerous CD, radio and television productions. In 2001 six of his compositions were published by the German Lute Society, and his tutor, "Figured Bass on the Classical Guitar" has recently been published by Amadeus
