[1] Despite most of his songs being written by Akio Inoue and composed/arranged by Daisuke Asakura (also TMR's former producer), T.M.Revolution is considered Nishikawa's solo project.

After three years as vocalist of the visual kei rock band Luis-Mary, Nishikawa debuted as TMR with the release of his first solo single "Dokusai (Monopolize)" (独裁 -monopolize-) in May 1996.

Several of Nishikawa's songs, such as "Crosswise" and "Flags", have been used by Capcom's Sengoku Basara video game series and media franchise.

His band nickname Haine (灰猫) and his appearance at the time would eventually become the inspiration for Nishikawa's character in Gundam SEED Destiny (Heine Westenfluss).

Nishikawa's performance on NHK's music variety show Pop Jam (which he would, later in his career, cohost for eleven months) helped boost sales, eventually selling out all first press copies of the single.

Nishikawa performed White Breath on the 48th edition of Kōhaku Uta Gassen, an annual music show televised by NHK.

Aoi Hekireki (蒼い霹靂, Blue Lightning), the first track from triple joker, was recut as a single in February 1998 and it was used in a Yamaha JOG commercial.

[11] Nishikawa's three albums were also released in other parts of Asia, and he visited Taiwan in April 1998 to promote triple joker.

The title track of the single was used as a theme song to a drama called To Make Divided a House (別れさせ屋, Wakaresase Ya).

"Thunderbird" inspired anime director Mitsuo Fukuda to ask Nishikawa to perform the first opening song for Gundam SEED ("Invoke").

Nishikawa also voice acted as Miguel Aiman early in that series and narrated a recap episode of Gundam SEED.

Nishikawa made his debut North American performance at Otakon in August 2003, to a massive audience who filled both the ballroom and overflow room (an exhibition hall) of the Baltimore Convention Center to their entirety.

Tofu Records released SEVENTH HEAVEN a few weeks later and Nishikawa performed at Pacific Media Expo in May 2004.

“Zips”, a track from SEVENTH HEAVEN, was used as an insert song for the first Mobile Suit Gundam SEED: Special Edition movie.

[13] Nishikawa was asked to sing the ending theme song of the Japanese theatrical release of Spider-Man 2 ("Web of Night"), because of his performance at PMX 2004 and his relations at Sony Music Japan.

Web of Night, released in late July 2004, also included a rearrangement of "Tears Macerate Reason" (originally from Seventh Heaven) and an English version of the song (translated by Lynne Hobday).

The surnames of both Nishikawa and Westenfluss mean "west river" in Japanese (西川) and German (Westenfluß), respectively.

The Vestige single came with a unique password that was used to vote online (on T.M.Revolution's official website) for which songs would appear on an upcoming self-cover album.

Ten songs were originally planned for this album, but due to the overwhelming number of votes, fifteen tracks were recorded instead.

The rearrangement of “Zips” was used as an insert song to the first Mobile Suit Gundam SEED Destiny: Special Edition movie.

[19] Named after the school where Radiohead met, ex-Wands guitarist Hiroshi Shibasaki joined the band alongside Sunao and Toshiyuki Kishi.

Nishikawa held the Real Time Countdown Party Revolution, a live concert he did with all of his fans on New Year's Eve, to make up for the lack of new T.M.

On March 24 T.M.Revolution will release a collaboration work with the Gundam franchise called "T.M.R.×GUNDAM SEED SPECIAL PROJECT [X42S-REVOLUTION]" The CD will contain all the 5 songs he made for the series.

It consists of 15 tracks including "Flags", "The party must go on", and "Count Zero", which are all songs he collaborated with Sengoku BASARA, as well as "Summer Blizzard" and "Heaven Only Knows ～Get the Power～", which were only released digitally.

[23] On March 6, 2019, Nishikawa released the album Singularity, which includes "Be Affected", his collaboration with Fear, and Loathing in Las Vegas, the Hiroyuki Sawano-produced tracks "His/Story" and "Roll The Dice", and the digital single "Unbroken" feat.

This past October, they served as the opening act for Nishikawa's band, abingdon boys school, at the Ebisu Liquid Room.

Nishikawa's radio show was broadcast on Monday nights and ran for eight years and nine months, from January 6, 1997, to September 26, 2005.

The company is responsible for artist management & promotion, operating Nishikawa's fan club, and marketing the DEFRÖCK brand (see next section).

[9] On a side note, in Gundam SEED, the Defröck label appears on Nishikawa's character's mobile suit as a custom sticker.

Nishikawa married fellow musician and singer Yumi Yoshimura on April 2, 1999, but the couple later divorced on July 1, 2002, after just three years of marriage.
