It was definitely worth attending, but also they mentioned several more upcoming appearances, especially as the Day of the Dead approaches.
Today, October 12th, they are at the Washington County Museum for the Free Family Morning. They will be there until 1 PM. That doesn't allow a lot of time, but it is also worth noting that the museum also has an exhibit of artwork by Huehca Omeyocan member Eduardo Cruz on display.

On October 26th they will be participating in a Hispanic Heritage Celebration at Linfield College (Rutschman Field House) from 1 - 5 PM. I cannot find a link for that.
However, there is information online about the Portland Art Museum community celebration on November 2nd from 4 - 9 PM. https://www.facebook.com/events/portland-art-museum/community-celebration-d%C3%ADa-de-muertos/293413464592728/
They also mentioned having ofrendas at each performance, as well as one at the Oregon Historical Society. (There is a different but related event there on October 22nd. https://ohs.org/events/sounds-of-the-living-and-language-death.cfm)
Even if these events is not possible, presentations can be scheduled through the group's Facebook page.
