100%WET add Sanna Heinstedt permanently with new single “Indigo”

By Tom Whitfield

Sanna Heinstedt is now the third permanent member of Copenhagen trio 100%WET, whose latest single “Indigo” is out now through Crunchy Frog Recordings. The announcement gives no calendar date for the single.

It makes the personnel change look less like a new arrival than a delayed formality. Heinstedt, also known as ASA Eir, has already appeared on 100%WET’s early single “Ether,” contributed to recordings and performed at almost every live show for more than a year. The permanent lineup is:

• Casper Munns
• Sanna Heinstedt, also known as ASA Eir
• Jakob Birch

The announcement provides no detailed personnel credits, release date or account of when the band formalized the decision. Heinstedt does not speak in the supplied material. That absence matters because “officially joining” can otherwise blur the difference between a business arrangement and an established creative role.

100%WET’s announcement describes “Indigo” as built around lush, reverb-soaked guitars and subtle Eastern musical influences. It brings Munns’s and Heinstedt’s voices together in what the band calls a dreamy arrangement, intimate and enormous at once.

The group has spent years developing its hybrid sound, which it names “hypergaze”: shoegaze, alternative rock, trip-hop and futuristic electronic production. The track’s guitars recede into effects while its beats continue moving.

The song also carries a change in feeling. According to 100%WET’s account, Munns wrote it from “a place of desperate longing,” then later heard it as a celebration of love and life. He said: “I like that it can be left open for the listener to bring their own meaning to it.” The announcement does not date either stage of that process or explain how the arrangement changed around its new meaning.

Behind the release sits a more serious interruption. 100%WET report that Munns was hospitalized with a rare, life-threatening illness and placed in an induced coma. The episode interrupted their creative plans and forced cancellations, including an anticipated UK live debut. The announcement does not specify the illness or give hospitalization dates, and it does not say when the UK performance will be rescheduled.

Since the group returned, Heinstedt has taken an increasingly important role in the studio and onstage. Birch described her as a major creative force behind 100%WET’s developing sound. Munns said her voice fitted naturally beside the guitars and that continuing as a duo no longer reflected how they made music. Those statements establish a clear artistic case for the lineup, although the announcement offers no songwriting splits or detailed production credits to test it.

What does Heinstedt’s official status change for 100%WET?

It formalizes a working relationship that the band’s own account says has existed for more than a year. For listeners, the practical difference is that Heinstedt is no longer merely a contributor around the project: she is now part of the named trio. For 100%WET, the change aligns the official lineup with the creative process Birch and Munns describe. It does not settle how the division of work will operate, because the announcement supplies no contract, credit or release-plan detail.

The group’s background gives the project a clearer setting. 100%WET trace their roots to Copenhagen’s Rhythmic Music Conservatoire, which the announcement says has also helped nurture ML Buch, Smerz, Astrid Sonne and Clarissa Connelly. Their self-titled debut introduced what the band calls its boundary-blurring approach and drew praise from KEXP, The Line of Best Fit and other tastemakers. The announcement quotes none of that praise, so it supports a claim of recognition rather than documenting its scale.

100%WET have also appeared at Roskilde and SPOT and supported Primal Scream. Those live credentials helped carry their self-described towering sound to live audiences, although the announcement supplies no festival years, set times or audience figures. Their later run included an inventive cover of Grimes’ “Delete Forever” and the original single “Eleanor’s Escape.” “Indigo” comes after both, with Heinstedt’s promotion and the trio’s altered lineup now attached to the song.

On the evidence supplied, “Indigo” presents 100%WET’s clearest account of how the new configuration works. Its claimed appeal lies in the meeting point of blurred guitars, restless electronic rhythms and two voices that the band says now belong together. The announcement leaves the song without a dated release, full credits or a detailed account of the writing process.

The next test is whether 100%WET can turn Heinstedt’s formal membership and Munns’s return from a life-threatening illness into new work.
