In this nice project, I created a logo for a Californian rock band. They wanted something that looked like sound waves, with some California groove.
I did the sketch at Procreate (and recorded this cool time-lapse video) and after that went to Glyphs for precise vectors. To the last touch, I used Illustrator.
