Recording engineer since 1993, when he graduated from Music Tech vocational college in Minneapolis, USA. He began his career at Pachyderm Studios, where he made excellent coffee and then proceeded to hone his studio chops by assisting on projects such as Live’s million seller Throwing Copper. He worked his way through various Minnesota rock’n’roll factories, before he found a more permanent home at Prince’s Paisley Park Studios, whose personal engineer he became and remained for four funky years. During this period he wasn’t only responsible for His Purple Majesty’s recordings, but also for the studio affairs of world renowned artists, including No Doubt, Chaka Khan and Larry Graham. Being a native of Germany, Hans-Martin Buff relocated to his home country in 2001, where he continued his career as an independent recording engineer, and where he has since mixed and recorded a host of national and international talent, such as Mousse T., Yvonne Catterfeld, Zucchero, Eric Burdon, Roachford, Maxi Priest and Scorpions.
