The Nth Power is a New Orleans?rooted trio harnessing the healing power of music. Featuring guitarist Nick Cassarino, bassist Nate Edgar, and drummer Nikki Glaspie, the band blends soul, funk, rock, and R&B with intricate multi-part vocal harmonies and virtuosic musicianship, creating performances that inspire dancing, deep listening, or pure goosebumps. Formed during Jazz Fest, The Nth Power made a splash with their 2013 EP Basic Minimum Skills Test and has since released two acclaimed studio albums and two live records, earning national coverage from Relix, Modern Drummer, Huffington Post, Glide, Consequence, Paste, and SiriusXM. Individually, the members have collaborated with artists like Beyoncé, Snarky Puppy, Maceo Parker, Dumpstaphunk, Big Daddy Kane, and John Brown?s Body. Their electrifying live shows have captivated festival audiences at Electric Forest, High Sierra, Peachfest, North Coast, and Hulaween.
