CHWALAW is an electronica project FORMED BY Welsh singer-songwriter Efa Supertramp and London-based producer Nick Ronin.

It started with ‘Diflanu’, a collaborative Welsh-language electronica single released in August 2021 – that also featured harp and additional composition by mid-Wales based Cerys Hafana. The single was voted number 4 on Siart Amgen (alternative chart) 2021 BBC Radio Cymru (Wales).

Since then Chwalaw has started work on a recording project with musicians in Germany who speak the minority-language Sorbian. As a development of this Arts Council Wales funded project we created a single and music video for the track Dim Arwyr (No Heroes) that features Welsh-language rap-vocals from Izzy Rabey, harp from Cerys Hafana and violin from Paul Geigerzähler.

‘Dim Arwyr’ has been played on BBC Radio 6 by Tom Robinson and BBC Radio 3’s Music Planet. You can check out the video below – directed by Izzy Rabey and filmed by Gabi Norland.




‘Space’ Series
I’m currently working on my third zine on autonomous spaces! They are very much inspired by the great venues and DIY spaces that I get to play when on tour around Europe. The first two issues Give Me Space (2016) and Taking Up Space (2017) are currently sold out, but might be available from my BigCartel page again in future.



Killdren sit uneasily between straight-up nihilism and fresh-faced naivety, penning politically charged slapstick anthems. They form the ideal soundtrack to the worst generation in history. Since forming in 2017 Killdren have played gigs at venues, dingy free parties, festivals home and abroad and released two EPs Overkill is Underrated (2018), Disguise the Limit (2019) and an album Dismembers of Parliament (2020) which they recorded during the Covid-19 lockdown.

Their tongue-in-cheek politically charged mix of rave music and punk sensibilities is a nod to the existing back catalogue of the two primary band members Efa Supertramp and Nick Ronin. The former is a singer-songwriter who is part of the European DIY
punk scene with her solo folk-punk act. The latter is a electronic music
producer, live performer and free party veteran. Each brings their
own energy and talents into the project and they choose to use their
uniquely spiky and fun rave-punk fusion to project their political outlook
and thirst for change.

“From sweat scraped from Atari Teenage Riot and using Bikini Kill as a surrogate womb before turning the Beast loose at Keith Prodigy’s wake, the 2-bit rave-punk duo have
birthed a twisted sonic chimera…” – Freedom News

I appeared as a guest vocalist on Grand Collapse’s incredible hardcore punk album Along The Dew.I was super chuffed to be asked to do this by these lovely Welsh lads because they are one of my favorite punk bands!

“Her contribution is outstanding and she makes the song her own.”  – Razor Cake

“My personal highlight of the album is the song “Through Bloodshot & Blurry”, one of the longest tracks on the record. Top-notch lyrics and a guest appearance on vocals by the folk-punk singer Efa Supertramp. Efa’s female vocals are a great addition to Grand Collapse’s music and I’m totally hooked on this song.” – DIY Conspiracy



I’ve been collaborating with Clusterfuck on tunes for a couple of years, usually Flapsandwich plays me tunes he’s working on and I just come up with some lyrics and vocal melodies to go over the top – then he manipulates them and finishes the tracks off! I feature on ‘Speck Of Dust’ and ‘Fear’ on Mortal Coil (2015), ‘Paranoia’ on Pesticide (2017), ‘Stop, Drop & Roll’ on Cameltoe Disco (2020) as well as ‘The Factory’ which was only released on YouTube and featured on the computer game, ‘Shadows of the Rose Croix’.
