In celebration of Google’s acquisition of YouTube, CDM’s Adrian Anders has rounded up some of the best YouTube videos, from more Museum of Techno madness to mashups with legos, DJing with 45s, and behind the scenes of music production with Album Leaf.

First, some musical inspiration:

Anders: The Album Leaf - Making The Album “Into The Blue Again”, featuring Joshua Eustis of Telefon Tel Aviv on the beats. A really cool look into the creative process for one indie, electronic music influenced band.

Kirn: This band has really been one of my favorites of the year, between Eustis, a detailed attention to sound, and generally creative music making on acoustic, analog, and digital instruments. And I wish I could mix records in Iceland.

Legos, the ultimate prototyping material. Many of us have wished we could have music controllers that could be assembled and customized with the ease of Legos; the Lego-like Mawzer modular controller system got our hopes up but still doesn’t seem to have evolved into a product you can actually buy.

Of course, why build something that’s reminiscent of Legos when you could just build it out of real Legos? The stekgreif project has done just that, thanks to a team of three German students (as near as I can figure) named P. Zentis, D. Tzschentke, and G. Homann.
