First time using X-Particles. The red "lasers" in the background are small tubes shooting upwards with a emission material and the bloom effect directly from the Octane settings in Cinema 4D. I also tried out the BPM feature in Signal 1.5 from Greyscalegorilla. Worked alright to get the correct tempo but had to reduce the baked keyframes from Signal to get a smoother headbang.
