BiSH (ビッシュ), also known as Brand-new idol SHiT (Shinsei Kuso Idol, 新生クソアイドル), is a Japanese idol group under WACK that was founded in 2015.

The group was conceived as a successor to BiS, whose first generation had disbanded the previous year. However, they since developed their own identity, especially after BiS was rebooted.

They are often described as being "a punk band without instruments".

2015[edit | edit source]

On January 13th, 2015, Watanabe Junnosuke announced his plans to restart BiS, this time named "BiSH", and opened auditions to find members.

BiSH's starting lineup, Yukako Love Deluxe, Cent Chihiro Chittiii, Hug Mii, Momoko Gumi Company and Aina The End were announced on March 9th. The members' faces were obscured with black contact lenses and could not be revealed until they each attained 4,444 followers on Twitter.

With their debut album, Brand-new idol SHiT, scheduled for May, on March 25th, BiSH's first song, Spark, was released as a free digital single on Ototoy.

On April 3rd, Yukako Love Deluxe suddenly withdrew from BiSH. Her last-minute departure meant that an emergency recording session to replace her lines in Brand-new idol SHiT had to quickly be enforced.

In April, BiSH released a music video for the song BiSH: Hoshi ga Matataku Yoru ni, and more songs were released as free digital singles in the lead-up to the release of their debut album, Brand-new idol SHiT, on May 27th. By the time of the album's release, all tracks had been released for free.

On May 31st, BiSH held their first one-man live, THiS iS FOR BiS. During the show, they announced auditions for new members and a single to be released in September.

On August 1st, BiSH performed at Tokyo Idol Festival for the first time, however, their second day of performances was cancelled due to misbehaviour from their fans. The same happened to their sister group, POP. Despite this, both groups continued to be invited to Tokyo Idol Festival every year since.

On August 5th, Hashiyasume Atsuko and Lingling were announced as new members. Like the previous generation, their faces were obscured with contact lenses until they received more Twitter followers than Watanabe. However, Watanabe soon got impatient and lowered the follower amount to 5000.

BiSH's first single, OTNK, was released on September 2nd.

Towards the end of the year, BiSH's second album, FULL METAL JACKET, was announced with a planned release in January 2016. The album's name was later named to FAKE METAL JACKET. Like their first album, tracks from the album were gradually released as free digital singles leading to its release.

The album was released at a price of 299 yen without any prior advertising, and the surprise edition is packaged without cover art or a lyrics booklet, a reference to Kanye West's sixth album Yeezus.
