Laila Cathleen Neuman studied with Christa Pfeiler and Susanna Waleson, before completing her bachelors cum laude at the Conservatorio Giuseppe Verdi in Milan with Margaret Hayward. She continued her studies with Breda Zakotnik and Barbara Bonney at the Mozarteum in Salzburg, where she obtained her master's degree in Lied and Oratorio with honours.

She has taken a special interest in historical acting techniques, which she studied with Margit Legler en Reinhold Kubik. She is now is part of The Amsterdam Historical Acting Collective.

Historical Gesture and period acting also brought her in contact with the melodrama genre, in performances of Georg Benda's Medea at the Early music Festival in Utrecht and as Galathée in Pygmalion by J.J.Rousseau, in a production of 'Performing Premodernity' in the historical Cesky Krumlov Theatre and the Riddarhuset in Stockholm.

She sang her debut in Milan as 'Second woman' in Purcell’s Dido and Aeneas, then the roles of 'Melpomene' in Il Parnaso Confuso, and 'Atalanta' in La Corona, both by C.W.v.Gluck, in Salzburg, Vienna, and Copenhagen. She sang the titel role as in Didone Abbandonata by D. Sarri, with Orkiestra Historyczna, at the reopening of the baroque theatre in Valtice in the Czech Republic. She also performed the role of 'Tusnelda' in J.A.Hasse's Arminio, with {OH!} in the Czech Republic and in Poland. In 2019 she performed the roles of Galathée and Colette in a double bill performance of Rousseau's Pygmalion and Le Devin du Village, in the historical theatre of Confidencen in Sweden.

Recent international activities also include performances as a soloist in the Matthäus Passion, Johannes Passion, Oster- and Weihnachts Oratorio by J.S.Bach, the Stabat Maters by G.B. Pergolesi, L. Boccherini, and A. Scarlatti. With Jan Cizmar and Jean-Sébastien Beauvais she created Le Jardin des Plaisirs, performing at the Concentus Moraviae Festival, the 2015 REMA showcase in Prague, and at the Sastamala Gregoriana Festival in Finland in 2018.
