The Baltimore Consort used to do programs similar to this one, but The Harp Consort takes the production values and vocal artistry to an even higher level. From the opening, a highly rhythmic, sensuously melodic traditional Breton number, you're drawn into a world of earthy, folk-based music that's filled out with the colors of period instruments and brought to life by the expressive voices of singers who allow the flow and pulse of the language to shape phrases and create natural accents and inflection. The result is affecting, engrossing performances that convey what we can only surmise is a reasonably accurate realization of these ancient and justifiably enduring tunes.

The music of Shakespeare's England - ballad tunes, country dances and elegant consorts - seems at first to be quintessentially English. Yet many of these tunes, as popular dances or in the high-art variations of division music, were inspired by Celtic and Spanish styles. In variations, from 17th-century manuscripts and in improvised divisions, 'gypsy' ballads are metamorphosed into exquisite consort music.

This is an album of songs from Guernsey, an island off Cornwall but much closer to Normandy, and the music is as odd and captivating as the particular brand of French in which it is sung. The music, even to a not-particularly-sophisticated ear, seems a combination of Celtic twang and French charm, with unexpected springs of rhythm amidst melodies that are as graceful as swans.

As England's greatest composer of the Baroque, Henry Purcell was dubbed the "Orpheus Britannicus" for his ability to combine pungent English counterpoint with expressive, flexible, and dramatic word settings. While he did write instrumental music, including the important viol fantasias, the vast majority of his output was in the vocal/choral realm. His only opera, Dido and Aeneas, divulged his sheer mastery in the handling of the work's vast expressive canvas, which included lively dance numbers, passionate arias and rollicking choruses. Purcell also wrote much incidental music for stage productions, including that for Dryden's King Arthur. His church music includes many anthems, devotional songs, and other sacred works, but few items for Anglican services.

Thirteenth-century troubador Gautier de Coincy's blend of mystical religious poetry and the popular tunes to which he set his poems proves irresistible, especially in the Harp Consort's lively renditions. Given the nature of the material, the sheer variety of rhythms, sounds, and colors on this disc is astounding; the vocal soloists are all excellent, the small chorus adept, captivating when it sings in the gutsy peasant style at appropriate moments. Eight purely instrumental numbers are sprinkled throughout the 20 tracks, each a gem, full of colorful effects from the rich-sounding shawm and other period instruments like bagpipe, vielle, and a variety of percussion instruments that thump and shimmer in ways that make you want to dance.
