Dundalk band Just Mustard have unveiled the new video for 'Blue Chalk', directed and edited by frontwoman Katie Ball and filmed with the help of Sean McMahon.

The song was also produced by Ball, McMahon, and David Noonan. The video sees Katie swimming in blue lighting mingling with darkness, before she swims towards a bright light and immerses herself in red.

The ambient cinematic elements mingle well with the murky, intense lyricism: "Underneath, your only thought
Through glass eyes that can’t see/Underneath, the footsteps laid on your sky/Underneath, shadows the same/the colours lost/That can’t see."

"The song Blue Chalk defines the heaviness that the whole of ‘Heart Under’ exists beneath," Katie explains of the track. "The kind that comes with grief and you feel like you are trying to navigate life with the weight of the sea on your chest keeping you down. I wanted to make this video since we started writing ‘Heart Under’ and to me it visually represents a lot of the emotion in the album."

The Louth noise merchants landed in the Top 20 on the Official Irish Albums Chart for the first time, debuting at No.17 with Heart Under earlier this year.

The Dundalk band's second studio album – and their first since signing to Partisan Records – was described as a "thoroughly fascinating record" in Will Russell's review of the album for Hot Press.

"Comparisons to Seventeen Seconds-era Cure will also rightly be made, and there’s a good dollop of Aphex Twin in the mix as well," Russell wrote. "Regardless, the best advice is to quit the taxonomy, and explore the fresh territory this remarkable band are mapping."

They join the likes of Fontaines D.C., IDLES, John Grant and Laura Marling at Partisan Records, having signed to the Brooklyn and London-based label last year.
