Who or what is/are Ko Transmissions? I don't know, but the lengthy letter that accompanied the cassette release featured here tells a long, involved story of musical messages sent to planet Earth by the Ko people. Yes, we have apparently made contact with space aliens. You heard it here first!
Ko-core is all instrumental. The tape gets off to a good start with some lovely harp sounds. This is followed by a drummer-less rock band, and a vaguely Middle Eastern electric guitar solo. Those last 2 parts weren't too interesting, but @ 9:12 we get to an excellent passage of exotic tribal drumming backing more Middle Eastern sounding violin (?) and possible other stringed things - music for green-skinned belly dancers entertaining their masters on some far off planet.
Which is followed by spooky guitar drones that smack of vast interstellar voids. Fine stuff. Next up, some noodly guitar plucking; a lengthy track starts @ 21:00 with drums and what sounds like mbira, cowbell-y percussion, and some kind of ethnic flutes/woodwinds that sounds like an Irish pennywhistle made out of PVC pipes. Then: atonal guitar skronk. I like the oddly bent Residential noises that start around 32:00 and the ambient drone that follows it. Some Beefheartian proggy guitars are then called to prayer at Mecca, and we're done.
None of it sounds particularly extra-terrestrial, but neither does it sound like any standard musical styles, unless 'random weirdness' is now a genre. 44 minutes of inter-planetary communication here:
