Post-Bop / Contemporary Jazz
What's great about Hiromi is how her compositions balance moments of frenetic energy with more laid-back sections. This is a bit more upbeat Jazz music that I would usually find myself getting attached to, but I'm sucker for excellent use of rhythm and this music has it in spades. It gives everything a real, driving sense of purpose.
Avant-Garde / Classical
Hans Otte is a somewhat underappreciated pianist and composer. If names like Phillip Glass and Steve Reich appeal to you, I don't think you'd regret checking this guy out. I'll take a quote from the AllMusic review of this album, as it states the draw of this meditative music beautifully:
The floating harmonies, which are the result of unresolved unions of majors and minors in interaction with one another without dissonance, are hauntingly beautiful. The sense of pushing a note or a series of small chords into one another before allowing space to reclaim them is another hallmark of the work... This is deeply moving, mysterious piano music, like the Rosicrucian works of Satie or the later preludes by Debussy, or, in some ways, the Nocturnes by Chopin, without their reliance on strict harmonic resolution, but in their convocation of intention and fascination with the mystery of sonic interrelationships.
This guy's 2016 debut album 'Cloak' has seen a return to my regular rotation. Its vibes are endlessly alluring and it has some nice subtleties and turns to its composition and musicianship that keeps it interesting throughout.
