For Lisa Schonberg, the process of composing music often starts with her body still and her ears open.

โ€œIโ€™m just, like, really into listening,โ€ Schonberg says over the phone, days removed from a trip to Brazil where she recorded the sound of ants, among other animals (she has a background in ecology and entomology).

โ€œIโ€™ll go somewhere and then just sit and listen,โ€ she says. โ€œSo I might go on a hike, and then every few minutes sit somewhere for a while and make field recordings at the same time that Iโ€™m listening and jotting down ideas… I have a lot of field recordings of the movement of a pencil, as well.โ€

Locally, at least, Schonberg is probably best known as one of two drummers (along with Heather Treadway) in the Portland big-beat punk band Explode into Colors, who were active (and beloved) in the late 2000s and reunited for a couple of shows last year. But this week sheโ€™s celebrating a debut with another long-running musical endeavor, Secret Drum Band.

Dynamics came out earlier this month on XRAY Records, but the origins of Secret Drum Band stretch back to 2006, when Schonberg put together a four-piece percussion ensemble for Ladyfest in Olympia. The bandโ€™s activity has ebbed and flowed (depending on material and available personnel), but solidified when Schonberg wrote a handful of songs based on recordings sheโ€™d made of rare bee habitat in Hawaii in 2013. Three songs from that project appear on the new album.

โ€œThatโ€™s when I said, โ€˜Letโ€™s try and be a band,โ€™โ€ Schonberg says. โ€œAn art band. A weird band. An experimental band. But letโ€™s get this thing going regularly.โ€

Dynamics is aptly named. Across eight tracks, Secret Drum Band builds a wall of rhythmic sound thatโ€™s sometimes dense, but just as often delicate. Schonberg and her fellow composers, Treadway and Allan Wilson (formerly of !!!), use the varying timbres of different percussion instruments to establish a meditative groove. Each song is filled out with strands of altered noise: affected vocals, noisy synths, and howling guitars, plus field recordings and samples of birds, wind, and electricity.

Some songs, like the transportive โ€œDaDaDa,โ€ grew out of typical basement jams, according to Schonberg. (She and Treadwell have โ€œcrazy percussive chemistry,โ€ she says.) Othersโ€”a slice of drum-driven disco called โ€œBig Metal,โ€ for exampleโ€”bear the clear mark of Wilson, whose work in !!! was decidedly dance-y. And when Secret Drum Band gets real weird, as on the groaning โ€œPepeiao Cabin,โ€ thatโ€™s usually an outgrowth of Schonbergโ€™s adventurous musical spirit.

โ€œSecret Drum Band, for me, is my means to exercise my own composition skills,โ€ she says, โ€œbut itโ€™s also been a really cool mix of writing with Heather and Allan. This album is kind of like the marriage of those two things.โ€

Thatโ€™s musically speaking, of course. For Schonberg, though, music has always been closely associated with place, the sounds of place, and the larger issues that affect us all.

โ€œSome people listen to bands from this country or that country, or this era or that era for inspiration, and I just decided at some point, โ€˜Let me see if I can combine all my interests… and engage people in environmental issues that are related to the work Iโ€™m doing,โ€™โ€ she says. โ€œAs someone who spent so many years in school tackling climate change, habitat loss, and all this stuff, it feels really good to use what Iโ€™m best at to try spread the message and awareness of these issues.โ€
