Holger Speck teaches singing and leads the vocal ensemble at the Hochschule für Musik Karlsruhe. This complements the vocal training in terms of a qualification for a professional activity in ensembles or choirs. He also works as artistic director of the Grammy-nominated, internationally renowned vocal ensemble Rastatt (www.vocalensemble-rastatt.de), about which the American Record Guide writes: "his ound is aking to pure gold". Holger Speck enjoys an excellent reputation as a charismatic, in many styles competent conductor, pedagogue and singer.
Both in the studio and on the podium convince his lively and compelling interpretations. Their characteristics are above all authenticity, stylistically adequate means of representation, an illuminated historical context, as well as a pronounced sense of sound. The "Fanfare magazine" (USA) certifies him an "undeniable authorithy". His numerous CD recordings with the labels Carus, Deutsche Grammophon and Capriccio are internationally respected and excellently discussed (among others: Fono Forum, Grammophone, American Record Guide, Fanfare, L'Orfeo, Pizzicato, Diapason, Classicstoday, Diverdi, Bayerischer Rundfunk, Broadcast Berlin-Brandenburg). He collaborates with outstanding artist personalities such as Hartmut Höll, Anne Le Bozec, Reinhold Friedrich, Veronika Skuplik, Wolfgang Meyer, Yannik Nezet-Seguin, Judith Steenbrink, Rolando Villazon, Edita Gruberova, Ruth Ziesak and others.
