Currently there are two events that I am aware of. 

1.  The Burke museum has an exhibition called Day of Reverence which talk about the Day of the Dead in Mexico along with three other cultures.

2.  There is a concert being presented by Seattle Pro Musica called: 

        A Spanish Christmas -  Here is their website

If you know of a Spanish language/culture event please email the information to me so that I may review it and share it with my classes.  Gracias.
