Ubeda's Misa is the first Uruguayan religious composition ever. He wrote it in 1802 and it is scored for four voices, flute and continuo. The manuscript (incomplete) is preserved in the archives of the San Francisco Chapel in Montevideo. The parts appear in an unusual order (considering the liturgic one):
01. Introito
02. Kyrie
03. Gradual
04. Dies Irae
05. Ofertorio (sic, in Spanish)
06. Sanctus
07. Benedictus

♫ 01. Introito

About the recording (Caprice CAP 21688 (Sweden) Hy Hy Hy Hy Hy Hy Hy Hy The New Jungle Book of the Baroque by Ensemble Villancico:
The cd contains examples of early baroque music from Central and South America, both sacred and secular, performed by a vocal ensemble with virginal, plucked instruments, flutes, viola da gamba and various percussion instruments (some native and exotic). Spanish, Chiquitano texts. Ensemble Villancico; Peter Pontvik.

The "Agnus Dei" and the "Communio" are missing. It has been recorded just once (to my knowledge) in a modern transcription by the Uruguayan musicologist Lauro Ayestaran and the composers (also Uruguayan) Vicente Ascone and Alberto González. Ayestaran also contributed a reconstruction of the missing soprano part.
Unfortunately the requiem is not available on CD. It was recorded during what might have been the only live performance (at least modern, it is unknown if it was performed during Ubeda's life) as part of an extensive series of concerts dedicated to neglected Uruguayan composers, during the 1970s. It was released in a Long Play, being one of a 3 LPs in a case, summarizing that series, by a local Record Company during the 1970s. It is very difficult to find a copy of those record, since LPs are no longer produced in the country and no one (not even the National Government) has decided to transfer them to CDs. It used to be broadcasted by the National Broadcasting Company (a State managed enterprise). It is a very simple work, since Ubeda was just an amateur composer, and the performance lacks good quality.
