Daniel Frank made his operatic debut as John Sorel in Menottis The Consul at Folkoperan in Stockholm in 2009. Before that, he had worked for ten years as a rock singer, vocal coach, music and drama teacher. The Nordic opera world became quickly aware of this charismatic performer and his powerful and wide ranged voice, and the debut was followed by selected baritone roles at Folkoperan in Stockholm, but also at other venues such as Läckö Castle Opera.

In spring 2010 Daniel Frank sang the part of Severin in Kurt Weill’s Silver Lake which successfully established his change from the baritone to the tenor repertoire.

Daniel has won several prizes, a. o. an award from the Friends of the Folkoperan “…for his performance in Pearl Fishers (Nourabad) and Silver Lake (Severin), two diametrically opposed sets and works, where Daniel Frank demonstrated a powerful range of singing and acting," and Uppsala Municipality Cultural order "… for his mature vocal art and theatrical portrayals on the opera stage, not least in the past performances "Pearl Fishers" and "Silver Lake" at Stockholm’s Folkoperan."
