New Orleans’ musical legacy includes a wealth of piano players, from Jelly Roll Morton and Fats Domino to Dr. John and Allen Toussaint. While not exactly a household name, Toussaint is something like a god among musicians, being one of the creators of R&B and early rock ’n’ roll. He’s also a fierce devotee of his hometown and its musical heritage, both of which he celebrates in “Keys to New Orleans,” a one-night-only piano triptych that includes two of his descendants. Henry Butler is a blind bluesman known as “The Pride of New Orleans”; Jon Cleary, a British-born pianist, has spent nearly 30 years living in the city and absorbing its blues, soul, and funk. Each will play solo tonight, portraying three generations of pianistic thinking from the city where the American musical tradition began.
