In the organizer's words:

SWR Summer Festival 2024

It's that time again: The SWR Summer Festival in Stuttgart from 17.05. - 20.05.2024 goes into the next round. You can look forward to lots of SWR programs, such as a unique Tatort premiere and the SWR 1 Pop & Poesie Special Show.
Selected comedians, presented by SWR3, will provide a good dose of fun on May 19!
Oliver Pocher presents the best from his new program "Der Liebeskasper".
Christoph Sonntag will also be at the start. His promise: The audience will laugh tears while he throws cabaret kicks in all possible directions. This evening's host will be SWR3 comedy boss Andreas Müller. With his brand-new live stage programme "washatterdann", he parodies, politicizes, caricatures, abstracts and makes music for all he's worth.

SWR will also be bringing a festival atmosphere to Stuttgart's Schlossplatz in 2024. In addition to a free daily program, there will be great live concerts in a unique setting.
