Specializing in 70's rock, punk and psychobilly, Psycho Nerds differs slightly from its sister stores in the Chaos Punk Co Ltd. franchise. The basement store is located in the teen shopping district Ximending where fashion punks commonly sport merch for bands they've never listened to, yet inside the shop you'll find staff that do know what they are talking about. While the theme of Psycho Nerds is 70s rock with lots of Kiss and AC/DC memorabilia on display, they carry much of the same subcultural gear as Chaos punk.

Under the parent company Chaos Punk, Psycho Nerds has sponsored Leek Record's recent Anti-Pop! events and acts as a ticket seller for shows at the Vicious Circle music bar and other events organized by Chaos.
