All-4-One in Rancho Cucamonga

All-4-One is an American pop and R&B vocal group formed in California in 1993. The quartet became known for close-harmony ballads including “I Swear,” “I Can Love You Like That” and “So Much in Love.” “I Swear,” from the group’s self-titled debut album, earned a Grammy Award for Best Pop Performance by a Duo or Group with Vocals. All-4-One joined the I Love the '90s Tour, performing on a rotating package that also featured Vanilla Ice and Color Me Badd. The group later took its four-part vocal set to Mexican arenas as part of The 90's Pop Tour, including Arena CDMX in Mexico City.
