If you want to see a show while you're in town, try and grab some tickets at Tonhalle Duesseldorf in Stadtbezirke 01. If you enjoy the show and want to see another, Duesseldorf Opera House, German Opera at River Rhein, and Tonhalle Concert Hall are all a short walk away.
Museum Kunstpalast is just one of the attractions in Stadtbezirke 01, Düsseldorf so you might want to stop by during your trip. If you want to experience more of the culture Düsseldorf has to offer, head to NRW-Forum Düsseldorf, Tonhalle Duesseldorf, and North Rhine-Westphalia Art Collection.
