I’m on record in the comments as having said Pizzicato Five’s pre-1994 material is of questionable merit. Well, I have to take it back a little, because I forgot completely about 1991’s Hi guys! Let me teach you. It’s an über-smooth instrumental set, with a jazzy groove and a relaxing downtempo lounge feel.
It was recorded as a soundtrack to a japanese tv show and is surprisingly hard to find. so if you run across a copy somewhere, pick it up.
