HEAR THE QUALITY OF ROBERT HENKE'S TEXTURES

April 20 is apparently a big day for those who like to partake of herb. Unsurprisingly, many of the mouths of Seattle's electronic-music community are frequently clamped onto bongs. Tonight's event, dubbed Textures, features some of the city's and the world's foremost fabricators of tactile, (mostly) beatless sound. Locals Seiche (aka Eric Moon) and Randy Jones will combine for an audiovisual performance while Berlin's Robert Henke (aka Monolake) will do the same solo and in surround sound. Henke is simply one of the planet's most skilled sculptors of both ambient and techno music. The tracks he records under his own name favor forbidding soundscapes that vividly evoke the elements in extremis. There's a good chance you'll wind up checking Re-bar's ceiling for rain and hanging icicles. With Michael Manahan. Re-bar, 9 pm, $12 adv/$15 DOS, 21+.

SUBMERGE YOURSELF IN MONOLAKE

When Monolake (see Wednesday's blurb and Stranger Suggests for more elucidation) gets behind the controls, the venue he's playing becomes saturated with an overwhelming sense of 360º awesome. Simply put, Monolake's techno tracks seem to come at you from all directions, flinging glittering percussive and textural debris at your head with great stealth and artistry. He is perhaps earth's foremost master of subzero, dubwise techno, a molecular scientist of sound who can inspire you to dance in paranoiacally novel ways. With Justin Timbreline. Baltic Room, 9 pm, $12/$15 DOS, 21+.

PLAN B MIGRATES FROM GRIME MC TO SOUL MAN

Plan B began as a hard-knock rapper who came up through England's grime scene (his tight, tense DJ Wonder–produced track "Cap Back" appears on the Run the Road comp) and dropped a vibrant, eloquent debut album in 2006, Who Needs Actions When You Got Words. On his 2010 album, The Defamation of Strickland Banks, he morphed into a slick singer/rapper who comes across like a UK version of Mayer Hawthorne and Eminem. Plan B's soul/hiphop fusions are nothing new, but they're executed with panache and the sort of professionalism that deftly eludes schmaltziness. With Eliza Doolittle. Chop Suey, 8 pm, $12 adv/$14 DOS, 21+.
