Renowned for their unearthly vocal blend and virtuosic ensemble singing, the four women of Anonymous 4 combine musical, literary, and historical scholarship with contemporary performance intuition as they create ingeniously designed programs, interweaving music with poetry and narrative.

In addition to their unmatched medieval repertoire, Anonymous 4 has often reached out into the realm of contemporary music, and has premiered works by Peter Maxwell Davies, John Tavener, Steve Reich, and Richard Einhorn. The group has most recently expanded their repertoire to include traditional music of the British Isles and America.

Anonymous 4 has performed in major venues and festivals throughout North America, Europe and the Far East. The ensemble has appeared on numerous radio and television programs, including Garrison Keillor's "A Prairie Home Companion," "CBS Sunday Morning," A&E's "Breakfast With the Arts," and NPR’s “Weekend Edition.” Anonymous 4's award-winning recordings have attained unprecedented popularity, rising to the top of Billboard's classical chart, and selling almost 1.5 million copies worldwide.

JOHANNA MARIA ROSE spent her childhood in the village of Grand-View-on-Hudson (a stone’s throw away from New York City), reading lots of children’s books and fairy tales, putting pennies on the railroad tracks, and looking for sea glass and stones at the river’s edge.  While putting in her time as a Manhattanite, she earned a degree in voice from the Manhattan School of Music, as well as studying acting.  A long-standing love of early music then led her to an MFA in the Performance of Medieval and Renaissance Music from Sarah Lawrence College.  Her various hats in Anonymous 4 include sharing the work on language pronunciation research, adapting readings for the concert programs, and new music commissions. Having escaped from the city, she now lives in a house from the 1830s (in which there is not a single straight edge), not far from the scene of her childhood.  She spends happy hours in her little garden, trying to deter the woodchucks from eating all her flowers, the squirrels from demolishing the birdseed in her birdfeeder, and the woodpeckers from drilling holes in the eaves.
