 Seay, also known as "Big C", is a disciple of the Paul Chambers school of jazz bass playing which features a style of walking harmonically inventive bass lines in a robust manner by positioning strings relatively high from the fingerboard – a practice mostly abandoned by modern bass players because of its physical difficulty.In addition to Roney, Seay has recorded and/or toured domestically and internationally with several renowned jazz artists and groups including Art Blakey and the Jazz Messengers, Wynton Marsalis, Billy Harper, Chico Freeman, Lou Donaldson and the Smithsonian Jazz Works Orchestra.Seay attended Duke Ellington School of the Arts in Washington, DC, with Wallace Roney and Gregory Charles Royal in the 1970s and attended Howard University with them and pianist Geri Allen in the 1980s.
