Over 30 seasons, Piano Spheres has presented over 1028 works for piano, 135 premieres, by more than 520 composers from across the globe. These works include primarily solo works but also include duo piano, piano chamber music, and piano vocal music, comprising 98 premieres. The heart of their programming is the Core Artist series of concerts by Core Artists Vicki Ray, Aron Kallay, Thomas Kotcheff and Nic Gerpe, world renowned guest artists like Ursula Oppens, Lisa Moore and Jeffrey Kahane, and Emeritus Artists Gloria Cheng and Mark Robson. The PS Core and Emeritus Artists also mentor and spotlight the next generation of concert pianists through their Emerging Artist Series, now in its ninth season. With support from the NEA and the City of Los Angeles, PS artists mentor younger concert pianists in how to approach the study, analysis and performance of new works with their commissioned composers. Public workshops featuring the young artists, mentors, and commissioned composers are held prior to each Emerging Artist Series concert. In 2020 Piano Spheres began its Summer Jazz Series featuring public performances by well known local jazz pianists such as Gerald Clayton, Joshua White and Roger Kellaway, Jamael Dean and Paul Cornish, with outreach to underserved local communities.

In 2022 PS inaugurated the groundbreaking Stein Artist Residency for Underrepresented Groups (StARHUG), naming Dr. William Chapman Nyaho as Resident Artist for 2022/23, whose primary focus is the music of the African Diaspora. Our StARHUG artist for 2023/24 is legendary Los Angeles pianist Althea Waites who has dedicated her career to performing and recording the music of Black American composers. Our StARHUG Artist for 2024/25 is Dr. Andrés Jaramillo, who specializes in the music of LatinX composers.
