You're likely to hear lots of noise coming out of Olympia this weekend. While that might not be news to some, the strange sounds emanating from the city will be calculatedly noisy.

In its 19th year, the Olympia Experimental Music Festival features bands from near and far who favor experimentalism, texture, ambience, improvisation and psychedelia over straight-up rock 'n' roll.  The three-day ordeal will take over all-ages venue Northern in Olympia June 28-30. The festival will feature 18 different acts - many from Olympia, and the rest mostly spanning from Seattle to Portland.

Music begins on Friday at 6 p.m.

Friday the 28 will bring experimental band Giant Worm to the stage. Emitting sounds that can only be rightfully heard in Olympia or outer space, Giant Worm has been creating "fugitive soundscapes and musical journeys to elsewhere" for more than 30 years.

The schedule for Friday, June 28 is as follows:

• 6-6:40 p.m.: Noisepoetnobody/Sistutl (Seattle)
• 7-7:40: The Giant Worm (Portland, Olympia, Eugene)
• 8-8:40: JD Helwig (Portland)
• 9-9:40: Tone Dogs (Seattle, Portland)
• 10-10:40: The WA Trio (Seattle)
