The PDX Pop Now! festival features several days of all free shows. Look for it July 20-22, in inner SE PDX. The schedule can be found at: http://pdxpopnow.org/summer-festival-schedule.
These folks usually run a pretty tight schedule, so there is music going on almost constantly, alternating between the indoor stage and the outdoor stage. Since it's free you can come and go as you like.
Here are a couple times when we'll try to convene an actual meetup - i.e. meeting and talking to folks in the group. Come and say hello, meet a few fellow music lovers, and then follow the music!
Friday July 20 - outside at 10:00pm, before the start of the last outdoor set.
Saturday July 21 - outside at 5:15pm.
Hope to see a bunch of you there - Curt
