プロデューサーやエンジニアとして00年台以降の国内インディ・シーンの様々な重要作品に携わってきた橋本竜樹のプロジェクト。
’10年に自身が主宰するレーベルde.te.ri.o.ra.tionから発表したアルバム『How Many Friends Can Die Happily?』が静かに話題となり、翌々年にWHITE LILYよりCD化。
’14年には須田洋次郎（ミツメ）、PunPun（PunPunCircle）、YUJI ANDO（golf）、JUN（8okidz）をゲストに招きスタジオ録音した12インチ・シングル『doqu』をリリース。
前身名義のSWINGSET時代から作り続けられる、サイケデリック・ポップをベースに深い郷愁感を纏った音楽は、より一層の深化を遂げている。
A solo project by Tatsuki Hashimoto. As a producer/engineer, Tatsuki was involved in a number of milestone releases in the post 00's indie music scene in Japan.
His first album from his own imprint de.te.ri.o.ra.tion, titled "How Many Friends Can Die Happily", quietly gained popularity since the release in 2010. Two years later, it was released again in CD format from WHITE LILY.
In 2014, inviting a wide range of guests, including Yojiro Suda (Mitsume), PunPun, (PunPunCircle), Yuji Ando (golf) and Jun (8okids) to his studio, Tatsuki released a 12-inch single "doqu".
The music Nag Ar Juna makes is an extention of his former moniker, SWINGSET. However, his own deeply nostalgic music covered in the fog of psychedelic pop is only continuing to evolve, further and further.
