That is very well said
It's a situation similar to Plas Johnson being the featured soloist on Les Baxter's Jungle Jazz and African Jazz, except those came out under Baxter's name, not Plas Johnson's.
Both Cal and Lalo were recording artists at Verve during that period. I've always thought it was odd that both did not get equal billing on that one, considering the respective roles of the participants.
Either way, it is a gem and easily in my top ten exotica albums ever, along with Les Baxter's Tamboo and Robert Drasnin's Voodoo.
