Who is Halaka?
Who is the fish?
Who are the mackerel?
Who are the best?
First off: what is Halaka? Halaka is not a traditional music group (or any of the other terms that are interchangeable with that: band, orchestra, etc.) They aren't, for the most part, "professional musicians," even though they've all been playing instruments and creating music for most of their lives. Most of them have ever really made a living at it, though there were periods of time during which they took a stab at that, and there is at least one of them who does okay for himself as a recording engineer/producer. For the most part, though, for most of the lifetime of the band, the members of this loose, but tight-lipped, organization have made their livings working "regular" jobs, while primarily recording, and secondarily performing, music when they weren't busy doing other things.
So has the question been answered, about what Halaka is? Surely not. My research has led me to believe that either they really don't care exactly what they are, and moreso what people perceive them to be, OR they do care what they are, but they don't care to share what they know about it with anyone else. There might be an important difference between those two possibilities, but the answer is the same either way: I don't know.
Halaka, as a group (forgive me if this sounds contradictory, first saying they aren't a traditional group, then calling them a group... it's just words, after all,) create music, noise, visual art, and performance art on their own terms, apparently for themselves. They sell or give away pieces of their work - mostly as audio media like CDs, cassettes, etc. With the acquisition in recent years of computers, various pieces of audio/computer hardware, and software, they've been able to sink even deeper into their esoteric void than ever before. What they were doing with 4, 8, and 16 track tape before they can now do with a greater level of control... or so they tell me. With some of the results you might be hard-pressed to tell whether things were rehearsed and planned-out, or improvised and done by chance and/or accident, and whether or not anything, at all, is actually getting "better." But it seems to keep them busy.
For now: read about the history of halaka, which'll only get you so far before you're stuck standing in the middle of the highway, holding your sack and eating your teeth.
