[3] They initially worked together as what was to be a one-off unit in November 2012, where they performed live noise renditions of Bis' songs "eat it" and "nerve".
Both releases included one of ten trading cards featuring either a member of Bis or of Hijokaidan, and one photo with a group shot.
[8] A self-titled box set limited to 1000 copies and priced at ¥30,000 was announced in Japan and offered for pre-order, and it sold out before its September 3, 2014 release date.
It contains four CDs (the second self-titled album, the LP mix of the first album, Best Live Select and vocal and instrumental versions of the 30-minute piece "BiS_kaidan_3"), four DVDs and two Blu-ray discs featuring 11 live shows by the band (including collaborations with Tokyo Shock Boys, Soul Flower Union and the Genbaku Onanies, plus a Jazz Bis Kaidan performance), a photo book, a Last Official T-shirt (size M), and a piece of the sailor suit worn by a group member.
[9] The Specific label licensed the second album in 2015, also for release on 500 one-sided laser-etched LPs[10] as well as streaming and download on their Bandcamp page and retitled BiS Kaidan 2.
At a live performance at Shibuya WWW in August, they threw objects including chicken feet, buckets, their own underwear, and a pig's severed head into the crowd.
Here, they expanded on their usual performance by adding various stunts, including Tokyo Shock Boys vacuum-packing Toshiji Mikawa and Ten Tenko into a plastic bag.
