Underneath this respectable, suburban veneer lies a seething hotbed of decadence; behind a curtain of boring hides an orgiastic cacophony of richness. It's called jazz.

If Bobble Tiki were to count awesome Northwest jazz musicians on one hand, Greta Matassa would land on his index finger. She headlines the Pierce College Jazz Expo Sunday. Bobble Tiki's other fingers contain the other performers of the night - Thomas Marriot Sextet (tribute to Art Blakey), McTuff, Pierce College Jazz Ensemble and Pete Christlieb Quartet - plus a bunch of boogers.

It's a full day thing. From 1-5:30 p.m. the Pierce College Jazz Expo will host "clinics" by the performing musicians, with concert scheduled from 2:30-8:30 p.m. Clinics will go on simultaneously with performances, so plan accordingly. Musicians of all abilities and ages, as well as non-musicians, may attend the workshops. Musicians are welcome to bring their instruments to the clinic because some clinicians may ask students to participate.

Bobble Tiki would describe Matassa as a vocal chameleon. She can switch from low and husky to light and whispering and then surprise and delight with a sonic wail. She is known for her unique arrangements of old songs first performed by singers such as Frank Sinatra, Fred Astaire, Ella Fitzgerald and Billie Holiday.

"Pierce College is thrilled to be able to host its annual Jazz Expo, where people can listen to and learn from world-class jazz artists in an intimate setting," said Kareem Kandi, Pierce College jazz band director. Kandi, a saxophonist and composer, also leads The Kareem Kandi Band, a fact only those who eat boogers don't know.
