All-4-One is an American R&B and pop group formed in the early 1990s in California. The founding members—Tony Borowiak, Alfred Nevarez, Delious Kennedy, and Jamie Jones—quickly attracted the attention of major record labels due to their vocal harmonies and catchy melodies. Their self-titled debut album, released in 1994, contained the chart-topping single "I Swear," which achieved a remarkable eleven-week run at number one on the Billboard Hot 100 and won a Grammy Award for Best Pop Performance by a Duo or Group with Vocal.

In addition to "I Swear," the group released several other successful singles from their debut album, including "So Much In Love," "Breathless," "I Can Love You Like That," and "Someday," the latter featured in Disney's animated film "The Hunchback of Notre Dame". Following their debut, All-4-One released multiple albums, including "On and On" (1999), "A41" (2002), "Split Personality" (2004), and "No Regrets" (2009). These albums contributed additional hits such as "I Will Be Right Here," "Not Ready for Goodbye," and "My Child."

Throughout their career, All-4-One has received numerous accolades, including Grammy nominations for their singles "I Can Love You Like That" and "I'm Your Man." They also won an American Music Award for Favorite New Artist in the Soul/Rhythm and Blues category for "So Much in Love" and garnered several nominations for Favorite Soul/R&B Single and Favorite Pop/Rock New Artist.

In the late 1990s, following a rift between their label Blitzz Records and Atlantic Records, the group left both labels, which led to a brief hiatus. They returned in 2001 with their album "A41", released through AMC Records. This album included the top 20 hit "Beautiful as U" and marked a new era for the group, who spent considerable time touring Asia throughout the 2000s.

In 2009, All-4-One released "No Regrets" on the Peak Records/Concord Music Group label, which featured the Urban Adult Contemporary hit "My Child." In June 2015, they celebrated their 20th anniversary with the release of the single "Baby Love" as part of an anniversary album titled "Twenty+".

In February 2016, All-4-One joined the inaugural "I Love the 90's" Tour alongside other popular acts from the era, further solidifying their legacy in the music industry. While continuing to perform and record as a group, the members have also pursued individual projects, with Delious Kennedy releasing solo material and co-founding the Catalina Film Festival.
