ΔLΔHΔ (ALAHA) is a vibrational landscaping company launched by Dutch musician and songwriter Jurriaan van Oortmerssen.  From before he was born in a musical family, Jurriaan was continuously and gratefully exposed to classical music and 1960s pop music – mainly The Beatles. His father, the renowned organist Jacques van Oortmerssen (1950-2015), gave him his first piano lessons aged four.
