Ecotrust has announced the lineup for their summer event series, Sundown, which is a sort of street-fair/concert to celebrate and raise awareness for green living. These are always great events, free outdoor concerts that take place at the peak of Portland summer. For four Wednesdays in July, the lot next to the Ecotrust building will be the place to go after work, with good music and a "farmers market of ideas." Take a look at the lineup, which has some very good things indeed:

Wednesday, July 10: Onuinu, Adventure Galley
Wednesday, July 17: Portland Cello Project, Adam Shearer
Wednesday, July 24: Crystal Bowersox, Wayward Vessel
Wednesday, July 31: "Super Secret Special Guest" (announced 6/29), Genders

I don't know for sure who the secret headliner is for July 31, but I have a pretty good guess (hint: take a look for any Portland bands that are playing a big show on June 28, the day before the announcement).

Wednesdays in July; Ecotrust Building, 721 NW 9th, FREE, all ages
