Thanks to Father Zuhldorf, here is a link to a concert of music for Sarum Rite. According to the Trinity Church website:
The Trinity Choir, along with Guest Conductor George Steel, General Manager and Artistic Director of New York City Opera, perform Music from the Sarum Rite. These gorgeous compositions – taken from the elaborate and theatrical liturgy of pre-Reformation England – feature soaring soprano lines and rich choral textures by masters such as Robert Wylkinson, William Byrd, Thomas Tallis, and John Sheppard. Although rarely performed today, the Sarum Rite includes some of the most exquisite music of any age.
Here is a link to the program.
