On the surface, the inclusion of any pokémon is a fantastic idea. Most tamed (or trained) pokémon enjoy participating in activities with their human companions, even activities as removed from battling as making music, and allowing pokémon to engage in these activities has been proven to be beneficial for both the mental and physical state of the pokémon and trainer alike. The 60s and 70s especially were a fantastic era for this, as musicians began experimenting with not only styles but also instruments and musical technology to produce some of the most fascinating sounds of the last century. I myself can wholeheartedly recommend quite a few artists in this genre, including Rawst Berry Alarm Clock, the Grateful Duskull, and even more modern groups such as the Smashing Pumkin Berries.
However, as much as I appreciate the creativity and artistry many of these bands put into their work, many others have made highly questionable decisions for the sake of their craft. For example, there was the infamous Liverpool Wigglytuff Perish Song Incident of ‘69, which, as many fans of Castelia Fly know, resulted in the deaths of 24 roadies, 57 fans, 6 security personnel, the entirety of the Castelia Fly’s headliner band, and 2 nearby hot dog vendors, as well as the physical and psychological injuries of 137 others. In short, while there is plenty of evidence that supports making music with your pokémon, always do so responsibly.
