Consequence of Sound has the sad news:

The Julie Ruin have postponed their upcoming world after singer Kathleen Hanna suffered a relapse of Lyme disease. According to a press release, the riot grrrl icon has been advised to start a three-month course of treatment, which will prevent her from traveling.

The Julie Ruin was scheduled to play Seattle at the Capitol Hill Block Party on July 26th. They're planning to go on tour this fall, once Hanna recovers.
