Kaitlyn Raitz

New York native Kaitlyn Raitz grew up surrounded by an array of musical genres, finding each one more exciting than the next. These passions have led her to a career as a versatile cellist who is equally at home playing Schubert or Sondheim, sitting in on a bluegrass jam or reading a Beethoven string quartet, and performing on stage at New York's Carnegie Hall or Nashville's Station Inn.

Kaitlyn has worked with artists Frank London of the Klezmatics, tabla player Shawn Mativetsky, as well as numerous folk and jazz artists. Kaitlyn has been invited to join cellist Matt Haimovitz’s innovative, GRAMMY-nominated cello ensemble Uccello and has performed with them at Carnegie Hall and Berkeley's Cal Performances. In Nashville, she has recorded on sessions for video games and major motion pictures as well as various artists such as The Hues, Lucy Dacus, Robby Hecht and Caroline Spence. Most recently, she began playing with fiddler Ben Plotnick. The duo, Oliver The Crow, released their debut album in June 2018 to critical acclaim. She is also the composer in residence for the Lotus Chamber Collective in New York for the 2018-2019 season.

Kaitlyn holds a Bachelors degree and a Performer’s Certificate from Purchase College, State University of New York where she studied with Julia Lichten and a Master's degree from McGill University where she studied with Matt Haimovitz. She splits her time between New York City and Nashville, Tennessee. 


Ben Plotnick

Ben Plotnick has established himself over the last decade as one of North America’s elite fiddle players. With a variety of acts, he has performed across 4 continents. He has recorded on more than a hundred albums as a session musician, performed at arenas and festivals across the continent with country, folk, Americana and bluegrass bands, and produced 6 records for himself or other collaborative projects. As a classical player, he has performed as a soloist with more than one professional orchestra. As an old time fiddler, he has placed as high as 1st runner-up at the esteemed Canadian Grand Masters fiddle competition. Moving from Calgary to Toronto and eventually on to Nashville, Ben continues to perform with and record for countless cross-platform artists (such as Raffi, the Trans-Siberian Orchestra, Anne Murray, Brett Kissel, Paul Brandt, and extensive touring with Front Country, Sarah Jane Scouten, The Fretless and Oliver the Crow).

He was raised as a classical player in a house of professional musicians, and before moving on to pursue jazz music, Ben had already performed as a soloist with the Calgary Philharmonic Orchestra, won countless prizes at local and provincial levels, performed as a soloist for Queen Elizabeth the 2nd of England; all before the age of 19. Simultaneously, Ben was a member of the world renowned “Calgary Fiddlers’, touring the UK, Asia, all over North America and more, performing an average of 100 gigs a year. Ben now serves as the ensemble’s in-house arranger, arranging new tunes for the group constantly, from afar.

Studying jazz music, arranging and composition at Humber College in Toronto has put Ben in a unique position of “bridging the gap” between classical, jazz and various styles of fiddle music – a talent that has put him in great demand as an arranger, in particular for adapting jazz, pop, bluegrass and country tunes for string orchestras or quartets. His arrangements are being played by string orchestras and gigging quartets across the continent, not to mention nearly 100 arrangements being performed worldwide by the Calgary Fiddlers.

Ben is a full time member of and creative contributor to the critically acclaimed folk quartet The Fretless,  who won a Juno award for Instrumental Album of the Year in 2017, to add to their slew of other awards and accolades. He's also half of new acoustic string duo Oliver the Crow, whose debut album was dubbed as "inspired", "brilliant" and "powerful art at work" (NPR, For Folk's Sake, Atwood Magazine). His latest solo record, ‘Greenland’, is a collection of original Texas Swing tunes and songs released in 2016. He now spends much of his time in Nashville, TN, or wherever the road takes him.

“Jack-of-All String Co. did a really fabulous work on these tunes. So grateful for their musicianship and attention to detail.”

- Paul Zacharias, Dog House Studios

"Jack-of-All String Co. are easily some of the most talented, attentive and above-and-beyond musicians I have ever had the privilege of working with. Without a doubt, I'll have them on every project"

- Kristopher James

“Kaitlyn and Ben are so skilled, versatile, and creative, in addition to being a total pleasure to work with in the studio setting. I came to them with a vision for an original song, and the string arrangement and performance that materialized was such a beautiful translation of that. I left our studio session feeling that the song had been realized in a way that it absolutely could not have been without their contribution.”

- Rebekah Rolland 

“I’ve had the privilege of working with Ben and Kaitlyn on a few occasions & look forward to many more in the future! They’re talented, focused, & professional. After a friend that is well-connected in the Nashville community recommended them to me, they agreed to write and record cello and violin parts for my project. At times they were at home in a controlled setting, and others they were out on the road and found time to record in their hotel room (to help me meet my deadline,) but each time the recordings were top notch and beyond my expectations. I highly recommend them for your cello and violin recording needs!” 

- Andrew Wayne Smith

"Kaitlyn at Jack-of-all string co. was a joy to work with. We collaborated via email and she asked great questions while providing a quick turnaround time. Best of all, her arrangements were exactly what the songs needed. I will work with jack-of-all string co. on more releases in the future for sure!"
