His affiliation (initially through Bickert and Fraser MacPherson) with the Concord Jazz label of California brought him to international notice by the mid-1980s. He has toured with MacPherson (USSR 1981, 1984, 1986), the Woody Herman All Stars (Europe, Japan, Australia 1985), and the Concord All Stars (Japan 1987), and travelled 1988-9 with Oscar Peterson and, beginning in 1989, with Oliver Jones.
Wallace, who is valued as a strong ensemble player with heavy, yet buoyant tone and supple technique in the older-fashioned manner of a Ray Brown, appears on recordings by Bickert, the Boss Brass, MacPherson, McConnell, Noto, Archie Alleyne, the Keith Blackley/Michael Stuart Quartet, and others. His albums with the Concord All Stars and the US singer Rosemary Clooney are listed in the Bickert discography.
