Now this is interesting sounding gadget called Meinl Helix Bowl. It is... as you can guess... a metal helix attached to hollow bowl. By stroking or beating helix with a metal stick produces fascinating spacey sound.
I was supposed to put a sound example here but it evolved into a full track called Ins'allah which will be included in "Kallokontrolli" CD-r. Just wait until it gets finished. (UPDATE: ...fuck that, it is here)
