The William Warfield Scholarship Fund has long worked to encourage career advancement for African-American vocalists. Since 1977, the fund has helped voice students at Eastman School of Music pursue their craft with the support of additional financial aid. On Sunday, as an important annual fundraiser, the organization will present the concert "William Warfield: A Legacy in Music" at Kilbourn Hall. The program will feature the vocal performance of Eastman junior and mezzo-soprano Alicia Rosser, along with appearances by pianist-vocalist Thomas Warfield, the Mt. Vernon Missionary Baptist Male Chorus, and Strings for Success. William Warfield — an Eastman School alumnus and Grammy Award-winning singer and actor — is best remembered for his portrayal of Porgy in the George Gershwin opera "Porgy and Bess," as well as his performance in the musical "Showboat."
