I totally agree, music helps my mind relax and facilitates creativity. I find different styles of music create different drawing experiences as well. My husband often makes his own electronic music in our attic studio that we share and I like the repetetive rhythms as they help me zone into the fine details of my drawings. But I also love listening to the familiar songs from my youth that have helped shape my personality such as the Pixies and Sleater-Kinney with their drony guitars and harmonies as they bring out a confidence in my work.
BBC Radio 6 Music is a reliable source of eclectic inspirational music, but I agree that I miss the good old mix tape with all its nostalgic connections with people and places.
I am obsessed with birds. I have been building up a journal over the past few months of my sightings and bird doodles, which has been really fun! I am a big fan of Matt Sewell's bird illustrations too, so much personality: http://mattsewell.co.uk/
