Ozomatli bassist Wil-Dog Abers provides his gifted ear as a producer to the debut album of Sonny Singh. Chardi Kala, out on May 13, combines challenging rhythms with eclectic music and lyrics, some of which are pulled from Gurbani, which is Sikh devotional poetry. Singh’s vocals are unmistakably nuanced and robust, even if you don’t speak the language or understand the context. Singh’s prowess on trumpet moves his compositions to another level, and he and Abers bring in a cast of musicians befitting these challenging compositions. Check out the single, “Mitar Pyare Nu” and the title track. Chardi Kala will free your mind.
