HD-Buch is the documentary about the revolutionary Bluetooth Rock'n'Roll formation formed in Nickelsdorf in 2005. The Handydandy were a bluetooth-rock and noise group from Vienna, Austria / Los Angeles, California. They are one of the most commercially successful and critically acclaimed bands in the history of popular music. The band's principal members were Bauch Bernhard, Gross Luc, Kirisits Nicolaj, Savicic Gordan, Waldner Florian and Tschuli Staudach-Jefferson. The HandyDandy is a wireless rhizom. A real-time rock axiom based on asymmetrical network music synthesis. They are first of all stars within an upcoming and never emerging music scene, namely the Bluetooth rock'n'roll. Their body performance implies powerful and energetic electro-acoustic computer music. Each of their concerts are site-specific artworks themselves which this documentation proves.
