<title>Kahvi #189c: Alkor / The Background</title>
<annotation>perhaps my favorite from the ep - emotive, sentimental and heavily inspired by the soundtrack from bladerunner (at least thats how I see it). you can just see the rain falling. excellent.</annotation>

<title>Kahvi #189c: Alkor / A day without the sunset</title>
<annotation>chilled but with an interesting touch - authentic ethnic instruments. excellent production fitting old and new together spotlessly. Enjoy this one.</annotation>
