There are many Early Music groups around, both as supporting organizations and as musicians.  They offer wonderful blends of recorders and other early instruments, especially in the Renaissance and Baroque (and even earlier) eras which many of us know and love.  Here is a sampling of some we are familiar with and events they are planning.  You may also want to check the Concert section for performing groups.

Parish House Baroque
 is Colorado Springs’ Early Music Ensemble, specializing in the brilliance and diversity of music from the 16th, 17th and 18th centuries through historically informed performances. Drawing on varied sources of performance practice in interpretation and ornamentation of the renaissance and baroque, Parish House Baroque strives to expand the community of people who love Early Music and to foster the next generation of audiences for Early Music through performances, outreach and dialogue.  With a core formation of baroque violin, recorders, baroque cello, viola da gamba and harpsichord, Parish House Baroque has developed a reputation for highly expressive performances and compelling programming. Parish House Baroque is currently ensemble-in-residence at First Lutheran Church, Colorado Springs, Colorado.
Baroque Chamber Orchestra of Colorado
This local ensemble is also moving into virtual performance, in addition to their traditional recorded and video formats.  They are planning a live performance in January (conditions permitting, I assume).  Here is information on their next streaming performance along with their link.
