"Rumble Pack" is Andreas Märki and Philip Guillaume from Zurich/Switzerland. Both started their way first as DJs back in '96 on small parties in Switzerland. Some years later they started to produce their own music, and made an education at the SAE School in Zurich as "Sound Assistant" to get the basics of sound engineering. From that point things got more seriously and finally the first album called "Mirage" was released in 2004 on Millennium Records /UK. Read more on Last.fm
