Get something loud that can take a beating. Beyond that, punk amps should be able to handle a sound somewhere between classic rock and metal. The amp will live and die by how it produces overdrive, but you’ll need a more rounded sound that doesn’t have as much high end as well. If you buy something with multiple smaller speakers, you’ll be able to keep your high end definition without cranking the EQ to compensate.
Kakashi is another example of a great record that went into obscurity after its first pressing only to be dug out and rereleased by Better Days and Jet Set Records. Shimizu, a saxophonist and composer, worked with all kinds of musicians and collaborators, including Sakamoto and even artist Nam-June Paik. This record is deeply hypnotic and visits all kinds of soundscapes throughout, always with the saxophone placed at the center of attention.
