Carefully identified with bandleader Jimmie Lunceford, Wilcox arranged for the band at its ‘30s peak, and afterwards led the group after Lunceford’s death. Wilcox fulfilled Lunceford in the middle ‘20s while participating in Fisk School. He performed in Lunceford’s campus music group and caused bands in NJ around 1927. Wilcox rejoined Lunceford in 1929 and remained with him before bandleader’s death of the coronary attack in 1947. Wilcox co-led the music group for a while (with tenor saxophonist Joe Thomas), after that assumed sole command from January 1949; he held the music group going into the first ‘50s. Then worked being a soloist around NY, including a stint of almost a decade at Café Riviera in NY. With Teddy McRae, Wilcox founded an R&B label, Raecox, in the ‘50s. He also proved helpful as an archive company executive using the Riviera and Derby brands. Before his loss of life in 1968, Wilcox proved helpful in Canada with “Big Main” Russell Moore.
