Here’s an example: Schönberg’s Variations for Orchestra (1928): https://www.youtube.com/watch?v=g7wefv98lvo

12-tone serial music always sounds to me like it belongs in a film soundtrack — it works well as background because the serial method suppresses the creation of recognizable melody as a foreground element.

I'd recommend listening to Webern's Op. 27, it's a strict 2nd Viennese school 12-tone composition but also very expensive, I love it (although it works better in a concert setting then a recording): https://youtu.be/ZEtqEzPakxA?is=JgbN1lpHF1lxrXOT
