About Pentimenti


Pentimenti takes its name from “pentimento,” the original drawing or painting that is overpainted when the artist takes a new direction. Revealing new layers or original insights inspires our artists: tenor Aaron Sheehan, soprano Kathryn Mueller, John Lenti on guitar and theorbo, and Joanna Blendulf on viola da gamba.


Viol player and baroque cellist Joanna Blendulf has performed and recorded with leading period instrument ensembles throughout the United States and abroJohanna Blendulfad. She is currently co-principal cellist and principal viola da gamba player of the Portland Baroque Orchestra and has also performed as principal cellist of Pacific MusicWorks, Pacific Baroque Orchestra, American Bach Soloists, Indianapolis Baroque Orchestra, Apollo’s Fire Baroque Orchestra, and the New York Collegium. Ms. Blendulf is an avid chamber musician, performing regularly on major concert series and appearing on numerous recordings with her groups, including Ensemble Electra, Ensemble Mirable, Music of the Spheres, Nota Bene Viol Consort, Trio Pardessus and Wildcat Viols. She appears as a frequent guest viol player with the Catacoustic Consort and Parthenia. Joanna’s world-premiere recording of the complete cello sonatas of Jean Zewalt Triemer with Ensemble Mirable was released in 2004.

Ms. Blendulf's festival engagements have included performances at Tage Alter Musik Regenburg, Musica Antigua en Villa de Leyva in Colombia, the Bloomington, Boston and Berkeley Early Music Festivals, and the Ojai Music Festival, as well as the Carmel and Oregon Bach Festivals. Joanna is also sought after as a teacher and chamber music coach and has served as a classroom and private instructor at the University of Oregon and the Berwick Academy at the Oregon Bach Festival. As an active member of the Viola da gamba Society of America, she teaches regularly at viol workshops such as the annual Conclave, Viols West, the Young Players Weekend, and has served as a national Circuit Rider teacher. Ms. Blendulf holds performance degrees with honors from the Cleveland Institute of Music and the Jacobs School of Music at Indiana University where she was awarded the prestigious Performer's Certificate for her accomplishments in early music performance. Ms. Blendulf was recently appointed Associate Professor of Music (baroque cello and viola da gamba) at the Indiana University Jacobs School of Music.


John Lenti, described by the Seattle Times as "a joy to behold," is regularly beheld playing lute, theorbo, and baroque guitar with lots of orchestras, choJohn Lentiirs, and opera companies on both coasts of the United States, as well as in the interior, non- coastal part, and a few, coastal or otherwise, in other countries. While orchestral work as an accompanist and concerto soloist comprises most of his career, chamber music is John's primary interest and he enjoys touring with his groups Wayward Sisters, the I-90 Collective, and Ostraka, while appearing as a guest with many other notable ensembles. With various groups he is frequently heard on most early music concert series and at lots of festivals. His recording credits include several well-received albums with some of the aforementioned bands, and his liner notes, program notes, and lectures have drawn copious praise.

While his time is spent doing a great many things on a great many historical plucked instruments and teaching a bit, John's most intense musical love is the English golden-age lute song repertoire, and his sincere desire is to become the Gerald Moore of the lute (currently accepting applications for a quiet Fischer-Dieskau with no vibrato), once that becomes remunerative. His repertoire extends from the early 16th century to the present day, but his commitment to the music of our own time is negligible if not actually averse. A native of South Carolina, John attended the North Carolina School of the Arts and Indiana University, and he studied with Jacob Heringman, Elizabeth Kenny, and Nigel North, also receiving valuable guidance from Pat O'Brien, Walter Gray, and Ricardo Cobo. Since 2006 he has lived in Seattle.

She collaborates as a guest artist with the award-winning early music group Wayward Sisters, and has also sung operatic roles for Arizona Opera, the North Carolina HIP Music Festival, and Bach Collegium San Diego.

Kathryn’s honors include a GRAMMY nomination for her solo work on True Concord’s album Far in the Heavens, and prizes from the Oratorio Society of New York's Solo Competition and Early Music America's Baroque Performance Competition. In 2011 she was one of four fellows in the prestigious Adams Vocal Master Class at the Carmel Bach Festival. Kathryn has also recorded two GRAMMY-nominated albums with Seraphic Fire, and is featured as a soloist on Seraphic Fire’s best-selling Monteverdi Vespers of 1610. Kathryn was born in San Francisco, and began her musical studies on the edge of Arizona’s White Mountain Apache Reservation. She got her first pro gig – a section leader position at a church in Providence – during high school in Rhode Island, continued her vocal studies as an undergraduate at Brown University, and then earned a Masters degree in vocal performance from the University of Arizona. She is based in Raleigh, NC and is on the voice faculties of East Carolina University and North Carolina State University. www.kathrynmueller.com
