Appointments made to Principal Flute, Associate Principal Viola, Associate Principal Timpani/Section Percussion, and Second Bassoon positions

The St. Louis Symphony Orchestra and Music Director Stéphane Denève are pleased to announce the appointments of four new full-time musicians as the SLSO begins its 2022/2023 season, the orchestra’s 143rd.

The SLSO’s 2022/2023 season begins in mid-September with the annual free community concert in Forest Park. Throughout the season, Denève and the SLSO perform repertoire that spans genre and time and celebrates music without boundaries, offering a musical journey to places near and far, real and imaginary, physical and spiritual. 

The SLSO’s new musicians are:

Julia Paine, Second Bassoonist, joins the SLSO following appearances with a variety of orchestras including the St. Paul Chamber Orchestra, the North Carolina Symphony, Charlotte Symphony, the Louisiana Philharmonic Orchestra, and Oregon Symphony. A graduate of the University of Miami and the Shepherd School of Music at Rice University, Paine is a native of the Chicago suburbs.

Paine succeeds Felicia Foland, who held the Second Bassoon position for 31 seasons until her retirement at the conclusion of the 2021/2022 season.

Kevin Ritenauer, Associate Principal Timpanist/Section Percussionist and the Paul A. and Ann S. Lux Chair, was appointed to the SLSO following four seasons as a percussion fellow at the New World Symphony in Miami Beach, Florida. He has performed around the country with orchestras including The Cleveland Orchestra, National Symphony Orchestra, Kansas City Symphony, Atlanta Symphony Orchestra, and the San Francisco Symphony. He received his Master of Music from the Cleveland Institute of Music.

He has also taught extensively in the United States as well as throughout South and Central America. Roitstein received bachelor’s degrees in architecture and music from the Massachusetts Institute of Technology and a Master of Music at Rice University’s Shepherd School of Music.

Roitstein assumes the position formerly held by Principal Flutist Mark Sparks from 2000 to 2021.

He has recorded with the Amici Chamber Ensemble and the Toronto Symphony Orchestra Chamber Soloists. He has spent multiple summers as a violinist with the Santa Fe Opera and has also performed with the Calgary Philharmonic Orchestra. In the summers, Valdepeñas has performed at the Aspen Music Festival and School and Norfolk Chamber Music Festival at Yale.
