A beautiful Preludio Largo from Sonata VII of Ignazio Sieber.
This is from a collection of 12 sonatas, the first 6 of which are by Galliard and the second 6 by Sieber, resident of Rome. This particular movement is written in a lush Italian style and uses the expressive qualities of the recorder quite well. These are sonatas worthy of much more attention than they have received. Great Italian style with good technical challenges. 

This is an old recording from the 1970s or ealy 1980s.
Michael Lynn, recorder (I believe this is played on a Tom Prescott Bressan copy with original fingerings, made by Catherine Folkers when she worked in Tom's shop)
Edward Parmentier, harpsichord (harpsichord by Keith Hill)

This copy of the recording was extracted from an old cassette and has a few audio irregularities.
