[1] He sings in a unique style combining reggae, dancehall, R&B and soul, and in different languages including English, Bengali, Punjabi, Hindi and Arabic.

[3] In 2000, Mumzy started out in the UK garage scene at the age of 16, and was involved in pirate radio until 2003 when he left as he felt like a stranger (from which he derived his stage name).

[7][14] Mumzy is featured on two tracks on The Streets of Bollywood 3, a remix album by Rishi Rich, Hunterz and Kami K which mainly focuses on bringing Indian and urban music together.

Mumzy collaborated with several UK and internationally recognised desi artists, such as H-Dhami, Preeya Kalidas, Abbas Hasan and Malkit Singh.

[23][24] Much like his mentor Rishi Rich, Mumzy collaborated with his new protègè and the first addition to the Stranger Family, Junai Kaden,[25] on the track "Aaja Mere Naal".

[26] In 2012, Mumzy officially launched Stranger Family, a music collective with Junai Kaden, Char Avell, Tasha Tah and Ramee.

[29][30] However, due to poor ticket sales and issues regarding managing from Tiffin Beats Records, the tour was cancelled[31] and would eventually lead to the breaking up of the Stranger Family.

[35][36][38] In late 2015, Mumzy Stranger featured in Iksy's parody music video alongside Corner Shop Show, Humza Arshad, Bengali Blitz, Puremovements and Char Avell.

In March 2018, he featured in Humza Arshad's parody of the viral Nike advertisement, known as "Nothing Beats A Londoner", featuring notable Londoners from underrepresented minorities such as Juggy D, H-Dhami, Tasha Tah, Sevaqk, Bobby Friction, Raxstar, Tez Ilyas, Arjun, Steel Banglez, Char Avell, Jay Sean, Corner Shop Show (Islah Abdur-Rahman, Michael Truong, Can Snatchy Kabadayi) and Naughty Boy.

[42] Mumzy featured on Nish's debut album Identity, co-producing and singing on the lead single "Love Lost" and producing the song "Maa Baba".

[46] After Identity, Mumzy was featured on Master-D's summer single "Tumi Jaio Na",[47] both of which are considered part of an "urban Bangla movement".

The album, with hip hop and R&B songs in multiple languages, features Mumzy's previous collaborators Nish, Raxstar, Arjun, F1rstman, and Lyan as well as J Riley, Snap Capone, Corleone and Inkra Dabelle.

[48] In 2020, Mumzy Stranger was featured on "Gallan Kardi", a remix of Jazzy B's hit song "Dil Luteya", from the Bollywood film Jawaani Jaaneman.
