Stoned Soul Picnic dates from the earlier part of Roy Ayers' career as a leader, before he delved heavily into R&B and funk fusions and instead concentrated more on soul-jazz grooves. Ayers leads a septet including such big names as pianist Herbie Hancock, altoist Gary Bartz, bassist Ron Carter, and flutist Hubert Laws. The Laura Nyro-penned title track foreshadows Ayers' later forays beyond the boundaries of pure jazz, and the group keeps the groove percolating nicely throughout, making Stoned Soul Picnic one of Ayers' better jazz-oriented outings.
Composer and oudist Rabih Abou-Khalil generates variety and interest by bringing aboard different guest musicians for each album. The personnel on Sultan's Picnic is so similar to that of Blue Camel that one might expect them to sound similar. But there's a key difference in the presence of Howard Levy on Sultan's Picnic. Levy is a talented harmonica player who has done a lot of offbeat work, including a stint with Béla Fleck & the Flecktones. Despite the power of Charlie Mariano on alto sax and Kenny Wheeler on trumpet, this album is dominated by the idioms of the harmonica, specifically the jazzy, quirky, lackadaisical idiom popularized by Levy's work with the Flecktones. This domination is noticeable from the beginning, on "Sunrise in Montreal."
