Some explanation on the name I took for this page.
Birkenholz, Birch in German is my favorite wood. There are two birch trees in the yard at my folks, so I guess it comes from my childhood.
I thought that German word not only sounded good, but was easy to pronounce and remember since many people around the globe bear the last name "Birkenholz".
Drum speaks for itself.
Boutique is at the same time a word meaning "fine store" in French, my mother tongue, and an international English word going well with what I do my my drums.
