He was a founding member of the early 90s southern jazz-fusion group Col. Bruce Hampton & the Aquarium Rescue Unit with Jimmy Herring, Jeff Sipe and others that had a lasting and influential impact on artists for decades to follow. That led him to join the iconic southern rock group The Allman Brothers Band as their final bass player during their latter day lineup in the 1990s and into the 2000s. During his tenure with The Brothers, they earned two Grammy nominations for best rock instrumental in 2003 and in 2004. In 2012, Oteil received a Grammy Lifetime Achievement Award for his 15 year contribution to The Allman Brothers Band as the longest running bassist in the band’s history.
