There is currently (almost 1am) a massive electronic music and laser light show at Dajia Riverside Park (大佳河濱公園), which I can hear and see loud and clear from my apartment 4km away. Try calling 1999 to hear a recorded message about the noise complaints - this event was permitted by Taipei City to go on until 4am.
Keep the whole capital city up til 4am with blaring electronic music, great idea KP!
Definitely a whack thing in Taiwan.
