A finalist at the International Schubert Competition in Dortmund, Issler has also won several prizes at the Swiss Youth Music Competition.

In 2021, he undertook to record his signature programme, 'The World of Song', for the Montreux Jazz Festival China, held in the esteemed confines of the Schubertiade Hall. The World of Song was premiered in an immersive 360 Reality Audio Cinema at the Festival in Hangzhou, China, to great acclaim.

Trained at the Guildhall School of Music & Drama, London, with Julius Drake, and a member of Graham Johnson's Song Guild, Issler holds two master's degrees with distinction from the Zurich University of the Arts.
