The Black Keys, like many, many other bands, tour non stop. And exhaustion just hit em. They’ve cancelled all future gigs (well, a tour of New Zealand)
The few times I’ve benn on tour with a band (hi TV Babies!!) I found it a straight drag and NOT the life styles of the rich and famous it pretends to be.
The hi/low of life on the road is exhuasting by definition, the endless highway of truckstops and after parties wears you out.
To do it for years on end can kill you.
