Ah yes I love those vids! Apologies for the plug but we also had the pleasure of including track from MQ playing Sidrolz on our latest comp:
MQ’s performance on the instrument sounds simultaneously chaotically, serene and full of emotion throughout a lot of the recordings of it I’ve heard. Would love to hear someone else playing one to see if that carries through to other performers.
Also, the Sidraw looks and sounds amazing too.
