This adorable colouring book is by the Yellow Bird Project, a group of musicians and artists that make cool stuff to benefit various charities. The colouring book has various activities and artistic interpretations on band references.
Here’s my cheery interpretation of a Clap Your Hands Say Yeah! page. It reminds me of Chad Vangaalen’s music videos.
Colouring books are a lot of fun, but I found that I’m way too OCD and a perfectionist to find this a relaxing activity. I’m hoping nobody gets me anymore for Christmas because I’d never finish them.

I agree – these are fun but you only need one at a time! Way too many pages to fill in!!
and way too many details per page! (a kid’s one would probably be more therapeutic)
