Meet the musicians who make the music that makes our wonderful concerts!



is unique in the Denver metropolitan region – a vocal ensemble consisting of five male voices focusing on music of the Renaissance and modern period. The singers bring a joy of music to their audiences and have brought both early music and popular tunes to young and old alike. Solis performs in churches, concert venues, and works in collaboration with other arts organizations.

The group was established in 2016 with the name Uomini Vecchi. Solis continues to use a vocal lineup of soprano, alto, tenor, baritone and bass. This unique set of five male voices lends itself to music of the Renaissance.

Solis is working toward becoming a repertory ensemble for performances of new music written specifically for them. New pieces by up-and-coming young composers as well as published and well-established composers will be added to the groups repertoire. The singers are currently undertaking a recording project of the entire vocal motets of the Renaissance composer Orazio Vecchi, most of which have never been performed, let alone well as modern arrangements of popular tunes. The extreme vocal range of the ensemble makes listening to their recordings and attending their concerts fascinating opportunities for lovers of music from all times and places.
