A somewhat unusual group in the Shibuya-kei orbit in that they began as a sort of novelty, leftfield J-pop band that seemly set out to sound like  Akiko Yano (矢野 顕子) pursuing a rocksteady record. 

After a few LPs, Hi-Posi (ハイポジ) settled on a gentler sound, a delightful convergence of Disney-princess orchestral balladry and twee electro-pop.

With 1995's Body Meets Sing—an unconventional translation of the Japanese title,「身体と歌だけの関係」, which loosely means "a connection of body and song"—they evolved into dreamy downtempo trip-hop, gentler and warmer than their previous efforts.

Unfortunately, as usual, much of this isn't on Spotify in the U.S. However, a nice collection of material is up, and that is worth flipping through, particularly if paired with a few of the YouTube streams. 

The impression I get is one of the original members, Kenji Kondo (近藤 研二), wrote most of the songs and has always held the masters for the bulk of their 90s efforts, and while he eventually left, converting it to a solo project of vocalist Miho Moribayashi's (もりばやしみほ), he owned the masters, it's only this compilation that has its global streaming rights addressed.
