May 30th was U-BASS day at Musician’s Institute in Hollywood CA and two of the world’s most notable bassists appeared on behalf of Kala Brand Muisic to demonstrate and provide personal accounts of their experiences with the distinctive short scale instrument. At the invitation of Stuart Hamm, Program Chair-Bass Department, Kala arranged for renowned bassists Abraham Laboriel and Bakithi Kumalo to appear in the school performing arts theater where afterwards, students and faculty were invited to demo an assortment of Kala U-Basses.
Each artist spoke to the assembly and performed solo demonstrations on the bass, then joined together in an impromptu jam session with the finale including a three way jam with the added participation of Stuart Hamm. The entire event was filmed and can be viewed at Kala Brand’s video page at
