Seal
回到英國後，他搬到倫敦居住，興趣急速轉向。他開始為發展迅速的酸浩室（Acid House）聲音著迷，並立即買了一個羅蘭取樣器和Atari電腦。他見到了席爾，並與其為席爾的首張專輯合寫了四首歌：《Crazy》，《The Beginning》，《Wild》和《Violet》，加上B面的《Sparkle》。這張專輯的製作人，特沃爾·郝姆（Trevor Horn）是Sigsworth遇到的第一個流行音樂製作人。
Bomb the Bass / Hector Zazou
Tim Simenon也參與了席爾歌曲《Crazy》的創作，而後Sigsworth很快成為了Simenon樂隊“Bomb The Bass”的製作團隊的一員，聯合創作了英國排名第七的單曲“Winter In July”。他也與Simenon一同製作了Hector Zazou's1992年的專輯《Sahara Blue》，與法國知名演員 Gérard Depardieu共同演唱“I'll Strangle You”。Sigsworth隨後與比約克一同參與了Zazou1994年的專輯《Songs From The Cold Seas》。
[編輯] Talvin Singh在和日本鼓手兼製作人Gota Yashiki一同合作期間，Sigsworth結識了著名手鼓演奏家Talvin Singh。隨後他為Singh的現場音樂會演奏了合成器和大鍵琴，還參與了Singh首張專輯《Ok》演奏和混音。
BjörkSigsworth是通過Singh認識比約克的，也是因為Singh他成為了鍵盤手，隨後成為了比約克樂隊兩張專輯的音樂導演。Sigsworth將他對早期音樂的敏感帶到了比約克的現場演出和專輯錄製中，加入了大鍵琴，翼琴，regal和伴唱鍵盤的元素。Sigsworth的大鍵琴出現在專輯《Post》中歌曲《Cover me》里。翼琴則出現在歌曲《All Is Full Of Love》中，鍵盤在專輯《Homogenic》的歌曲《Unravel》里出現。《Unravel》是Sigsworth和比約克第一首合作的歌曲。據報導，這是Thom Yorke最喜歡的歌曲。Sigsworth還在比約克出演Joni Mitchell的《The Boho Dance》時演奏了鐘琴。之後，鐘琴成為了《Dancer In The Dark》(其中他參與了弦樂編寫) 和《Vespertine》 （其中他參與創作了《Hidden Place》，《An Echo, A Stain》, 《Sun In My Mouth》和《Harm Of Will》）兩張專輯的特點。
Imogen Heap在聽到一位朋友演奏了歌曲《Come Here Boy》的唱片樣品碟後，Sigsworth於1996年結識了Imogen Heap，他馬上愛上了她獨特的嗓音。同時，她特別鍾情於較廣闊，有稜角的間歇特點的旋律，特別是大七和弦和小九和弦。這些在流行音樂中是不常見的，對此Sigsworth很是驚喜。他們一起寫了兩首歌曲，《Getting Scared》和《Airplane》。這兩首都被收入Heap的首張專輯《I megaphone》中。作為回報，Heap在Sigworth與Alexander Nilere合作的樂隊Acacia中演唱和聲。
G:MT1999年，Sigsworth憑電影 G:MT - Greenwich Mean Time大獲成功。其中包括了Imogen Heap，Talvin Singh和自由爵士名手 Lester Bowie的加盟。
MadonnaSigworth參與製作了 Mandalay樂隊1998年的專輯《Empathy》，這吸引了麥當娜的注意，並導致他與麥當娜為她2000年專輯《Music》合寫了歌曲《What It Feels Like For A Girl》。Sigsworth還與 Jem一同為麥當娜2003年的專輯《 American Life》創作了歌曲《Nothing Fails》。
Frou Frou
在印度孟買的一天晚上，在此為英國亞裔歌手Amar製作歌曲的Sigsworth在他的山葉QY20掌上音序器上創作了一首旋律。他一回到倫敦便將此歌交給Imogen Heap，請她為此歌取名。隨後這首歌被命名為“Flicks”，成為了Frou Frou樂隊第一張專輯《Details》中的一首歌。起初，兩人並沒有組建樂隊的計畫，這完全是出於Sigsworth想聽到各種不同音樂元素得到展現的想法。Heap說：“大概每個月Guy都會給我打電話，說我有了一首新歌，你願意來唱嗎？這樣不知不覺我們就有了一張專輯。” 作為新出現的一系列歌曲的連結概念，Sigsworth對歌詞有兩點建議：
歌詞應該像一組對話，而不是歌手一個人的無聊獨白。啟發這個想法的是1932年 Jean Cocteau的 La voix humaine，（整個戲劇的台詞由一位女士和其情人的電話對話中的一端通話內容組成。她情人的聲音從未出現，但卻能從她的言語中推測出其內容。） “愛”這個字應該儘可能多的出現。 Sigsworth為歌曲《Breathe In 》《Only Got One 》《The Dumbing Down Of Love》創作了歌詞，並參與了專輯《Details》中《 Let Go》《It's Good To Be In Love 》《Psychobabble》歌詞的創作。除了《 maddening Shroud》是由Alexander Nilere 作詞外，Heap寫了餘下的歌詞。 在完成了11首歌之後，Heap和Sigsworth準備為他們的共同努力成果尋找名字。Sigsworth是個法語迷，想出了Frou Frou這個名字，Heap也很喜歡。這個名字來自1870年Rimbaud的詩歌《Ma Bohème》，是一個法語擬聲詞，原意為跳舞女士的衣裙發出的“嗖嗖的聲音”。專輯名“Details”，意指歌曲是在製作室里通過疊加細小聲音片段而製作而成的。 專輯於2002年由環球唱片發行。專輯大受歡迎，但銷量並不大。《Breathe In》是首先在國際上發行的單曲，並在義大利音樂廣播中排行第二，但接下來的單曲《Must Be Dreaming》和《It's Good To Be In Love》並沒有以商業模式在英國發行。他們還為《The Dumbing Down of Love》製作了一首mv，由Joel Peissig導演（他後來導演了Heap的個人mv，《Hide and Seek》）執導。二人在美國的巡演吸引了不少歌迷，但Frou Frou於2003年解散了。 Heap和Sigsworth臨時改革了Frou Frou，錄製了《Holding out for a Hero》的非原唱歌帶（原版為Bonnie Tyler演唱的怪物史萊克2中的插曲）。該電影的音樂導演找到了他們，他也是Frou Frou的歌迷。結果該插曲在電影末尾播放。Frou Frou在2004年再次崛起，原因是Zach Braff選用了《Let Go》一曲作為其電影《Garden State》的插曲。其他不少歌曲也被電視劇CSI，E星戀(Roswell High)等收為插曲。 雖然在發行一張專輯後就解散（Heap和Sigsworth仍然是好朋友，時常見面聊天，但各自專注於自己的音樂領域），Frou Frou的音樂影響力一直很廣，Heap與Sigsworth在他們的合作結束後，反而得到了更多關注。
