Warren is the founding host and producer of WRTI's gospel music program, Ovations. A Philadelphia native, he's been a musician since he was nine years old and grew up "in church" and "in jazz" - often sneaking off as a child to participate in jazz jam sessions on Saturday nights, and then singing hymns and gospel songs in the choir on Sunday mornings.
After studying at Oberlin Conservatory of Music, Warren emerged as a trend-setting pioneer within the genres of jazz worship and sacred jazz. As an arranger, composer, director, performer, and producer, he has been called "...an innovator who has taken significant strides in the fusion of gospel music and jazz...making all things new, and raising the bar in vocal jazz and praise performance..." by the Philadelphia Tribune.
Warren serves as minister of music for Broad Street Ministry (an arts outreach ministry in Philadelphia), and consults for a variety of ministry initiatives nationally. He's an elder, music minister, choir master and young adult leader at Oxford Presbyterian Church in Philadelphia, and conducts choral workshops and worship development seminars that explore the integration of jazz and contemporary aspects of worship.
Warren can be heard on Sundays from 6 to 9 am.
