Billy Murray (1877–1954) was perhaps the most prolific recording artist of the acoustic recording era. His distinctive nasal baritonish-tenor voice, which recorded extremely well, and his perfect diction contributed to the popularity of his records. During his career, Murray recorded for nearly every company in existence, most notably for Edison and Victor. Murray's repertoire, while confined to the popular idiom, was wide-ranging. He was most famous for Irish dialect comic songs, but he could also handle ragtime and African American dialect material with ease, along with sentimental songs and Tin Pan Alley and Broadway material. Among the repertoire in which he specialized were many works composed by George M. Cohan.
