In 2006 he moved to Vienna. With the „Mnozil Brass“-trumpeter Thomas Gansch, he launched the „Don Ellis Tribute Orchestra“ in 2008. In 2010 he founded his “Markus Geiselhart Orchestra (MGO)” with which he was the „stage band“ in the Vienna jazz club „Porgy&Bess“ in the 2013/14 season and released the critically acclaimed album „My Instrument is the Orchestra“ in 2016. In the same year he toured with the MGO and the exceptional American trombonist Ray Anderson and made guest appearances at the renowned „Ludwigsburger Schloßfestspiele“ (Germany), among others.
