What's This Called? features experimental and eclectic music of all genres. From John Cage to Sonic Youth, Merzbow to Autechre, Crank Sturgeon to Ariel Kalma, Sun Ra to William Shatner. You shouldn't be surprised to hear a classic electronic composition from the last century, played back to back with a droning wall of post-punk guitar feedback, followed by a saxophone improvisation from one of the giants of free jazz.

Beginning life in 1993 at KAOS in Olympia WA, What's This Called? came over to KPSU after a two year hiatus on August 27th, 2005. The show and the station have been a perfect fit, and host Ricardo Wang continues to marvel at the daring of KPSU to allow such programming on Saturdays in the daytime - a timeslot most other college and community stations devote to the likes of bluegrass music or car talk.

Throughout the tenure of What's This Called? at KPSU, original host Ricardo Wang has been regularly joined by Austin Rich as a live music soundman, preferred substitute, musical adviser and resource, and occasional sit down in the booth co-host. In 2010, Ricardo decided to make this official and declare Austin the show's permanent (at least for the foreseeable future) co-host. Think of it as when Jim 'O Rourke joined Sonic Youth.

While recorded music is the weekly focus, What's This Called? has hosted semi-frequent live musical guests as well including: The Silverman (of Legendary Pink Dots) with Soriah, Green Milk from the Planet Orange, Zoe Keating, Crank Sturgeon, Daniel Menche, KnotPineBox, Eet, Joy Wants Eternity, Mattress, Moodring, Boyd Andersson & Mukis, METAL, Argumentix with Kitty Midwife, Childhood Friends, In Gowan Ring, Shalloboi, A: Frequency, Mr. Pharmacist, Obe Skupla, L.A.
