Featured Artists!


Featured works for November 25th-December 2nd:

Featured Art!


The featured artist for this week is SaoR186, an up-and-coming graphic designer and artist on Twitter and Instagram, who began posting work relating to vocal synths and Kasane Teto earlier this year. If there’s one aspect of drawing I enjoy most, it’s the coloring and rendering that brings a finished piece together, so it’s no wonder that SaoR186’s taste for vibrant, high-contrast colors and additional texture work would catch my eye – the final product is nothing short of exceptional! Please send some love their way, via their social media listed above. They currently have commissions open, if you’re looking to support them more directly!

Featured Song!


“Girlving to the Right” was originally posted in January of 2015, making the song a decade old starting this year. Created by harufuri, it’s described as being about “a girl persisting with her ego”. A breakout hit, the song would later feature on the 2017 album “EXIT TUNES PRESENTS UTAUMiRAi”, an album focused specifically on songs with UTAU singers. This song would later see a cover from the Synth V version of Kasane Teto, posted to the TWINDRILL YouTube channel to promote the launch of the upcoming voicebank.
