Absynthe Minded originally formed in 1999 as a one man band. Singer/guitarist Bert Ostyn recorded the first demos solo in his bedroom in Ghent. In 2002 Ostyn recruited Renaud Ghilbert (violin, trumpet, percussion), Sergej Van Bouwel (bass, contrabass) and Jan Duthoy (Hammond, piano) to form the Absynthe Minded Quartet, shortly Absynthe Minded. The History Makes Science Fiction EP (2003) was their first release on the independent Keremos label.
One year later the band finished second the infamous Belgian rock contest Humo's Rock Rally, which gathered them a serious amount of media coverage. After the addition of drummer Jakob Nachtergaele to its line-up, Absynthe Minded released their first full length Acquired Taste later that year to much critical acclaim.
Their sophomore album New Day was released only a year later. With the succes of hit-single My Heroics, Part One, Absynthe Minded start touring Belgium, The Netherlands and Germany. They also supported dEUS on their European tour.
In february 2015 Absynthe Minded announced their split, due to solo ambitions of Ostyn.
