b. William D. Colleran, 26 April 1925, Pittsburg, Pennsylvania, USA. Colleran began his career as a teenager singing with Ed Brozi in a touring medicine show, and was influenced by acts such as the Monroe Brothers and the Blue Sky Boys. After World War II, he became interested in bluegrass music. In 1949, he and his band played regularly on WHJB Greensburg, Pennsylvania, and since there were three members of the band called Bill, he decided he would become Mac Martin. In the early 50s, he was noted for his banjo playing and fine vocal work, and in 1953, was playing with a band on WHOD Homestead, Pennsylvania, which was likened to that of Lester Flatt and Earl Scruggs. In 1957, he and his band took a residency at Walsh’s Lounge in Pittsburg where they played weekly for the next 15 years. In 1963, the Travelers recorded two albums for Gateway records, although only one was released. A few years later, they recorded four albums for Rural Rhythm. Noted mandolin specialist Bob Artis (b. 26 July 1946, Santa Monica, California, USA) joined the band and when Mac Martin left for a time in 1972, Artis took over. In 1974, when the band recorded for County, Martin had returned. In addition to his playing, Artis wrote many articles for publications such asBluegrass Unlimited and Muleskinner News, and his bookBluegrass was published in 1975.
