Lambert wears a striking wooden mask when he performs his original, minimalist piano pieces. He is a crossover artist between classical, jazz and pop, oscillating between Erik Satie and Keith Jarrett, and has also picked up the thread of contemporary pop musicians – he gives a new face to songs by José Gonzales, Tocotronic or Ja, Panik, while his own remains concealed, blurring the boundaries between author and interpreter.
