Vince Gill achieved his big breakthrough in 1990 with "When I Call Your Name." That heart-rending lament won both the Country Music Association's Single of the Year award and a Grammy for Best Country Male Vocal Performance. Since then, Gill has won more CMA honors. His high, pure tenor voice and unerring sense of harmony have caused dozens of artists — from Reba McEntire to Dolly Parton to Barbra Streisand — to embrace him as a duet partner.
