A lot of stuff: a mixture of old recordings I've had for a while and some new items just for kicks. Here goes in no particular order of preference or importance:
The Futuristic Sounds of Sun Ra (1961) is well-worthy of repeated play. Pianist/keyboardist Sun Ra and his band incorporate elements of hard bop, avant-garde jazz, and African music, producing something that still to this day sounds well ahead of its time. Also strongly recommend Angels and Demons at Play/The Nubians of Plutonia, which includes two albums recorded in the late 1950s. Angels and Demons swings like a very left-field hard bop album, while Nubians grooves to a much more experimental vibe. Each of these easily earn him the title of godfather of Kozmigroov.
Critical Mass (1995) is some ace contemporary free jazz featuring some of the finest musicians in avant-garde circles. There is a very meditative feel to this album.
I've been listening to The Complete Studio Recordings of the Classic Quartet which features tracks from 1961 through 1965. I've really enjoyed the boxed set, which sequences their recorded work in chronological order. My faves are the tracks for the album A Love Supreme, and a track on disc 6, "Ascent." All of the recordings of the classic quartet are worth owning, and listening to. I've learned a fair amount about music and life from these tunes. Also have been listening a lot to Interstellar Space, which features the duo of Trane and drummer/percussionist Rashied Ali. It's an intense workout, and well worth the time if you have open ears. Shows hints of a world music vibe, which I suspect would have increasingly occupied Trane's interests and playing had he lived.
I've been spinning Thembi, Pharoah's 1971 classic, which is very meditative and has a strong world fusion flavor to it. His gentle vision shines throughout the recording, and I walk away feeling like there may be hope for humanity after all - even if for only a moment. A related album by Sanders is Summun, Bukmun, Umyun (1970), which features considerably more percussion. Like any of his albums of the period, the tracks alternate between serene and explosive. Spritual in every sense of the term. In a word: groovy. Also worthy of many spins in my cd player: Black Unity (1972). I also have been playing Live at the East (1971) and Elevation (1973) on my mp3 player at work. Practically any of his work during the late 1960s and early 1970s is well worth seeking out.
I've been listening a lot to Village Life (1985) which features live-in-studio improvisations by the two artists. The sound is a fusion of Gambian folk music and electronic jazz/funk. The feel is much different from anything Hancock was doing during the 1980s: very delicate, intricate, meditative. Chances are, you've never heard anything like it. Sadly, this has been out of print for a long time.
Solomon's Daughter (1994) features the drummer in a quartet that includes Pharoah Sanders on sax (Phaoroah sounds very inspired on these tunes). Mostly in the spirit of 1965-1966 vintage Coltrane. Also been spinning Kairos (1996). This album is a nice follow-up, which again includes a number of quartet tracks (different sax player this time who keeps up every bit as well as Pharoah), as well as several brief world music tracks in which Kiermyer adds some drumming. Kosmigroov is alive and well at the dawning of the 21st century!
Music for 18 Musicians (1998) was recently re-recorded and issued on Nonesuch records. I heard an excerpt of this classic (on a progressive jazz sampler of all things) almost 20 years ago and was in awe. If you like ambient music, you'll love this album, which relies on acoustic instrumentation and vocals to create a mantra that sounds electronic in spots. Also have been spinning the Reich Remixed (1999) album. Hearing Reich filtered through the minds of trip-hop DJs is quite an experience -- very well-done.
