Tool is a rock band from Los Angeles, California.

In 2008, the band went on hiatus and in May 2013, they teamed up again to play at the Ozzfest music festival, which took place in Japan.

To celebrate the comeback, three posters were created as promotional items. All posters were inspired by songs from the album "10000 Days".

The colors and style of the illustration were inspired by the songs themselves, which carries elements of grunge, metal and psychedelic rock, and is often dark and existential.

All illustrations were done freehand in Adobe Illustrator CS6.
