welcome here on this site,
We are Daniëlle Bijland (Daan) and Harco vd Nieuwenhof (Double-up)
The artist name “Daan” is obvious from the name Daniëlle
“Double-up” is because i just sing only the leading vocals
but also the backing vocals, double me 😉
We both love to sing to anyone who likes to listen to us.
