Seedhe Maut is a hip hop duo from Delhi, India (Originally from Uttarakhand, India), consisting of Siddhant Sharma (stage name Calm) from Nainital and Abhijay Negi (stage name Encore ABJ) from Pauri Garhwal. Formed in 2015, their name comes from a slang that the former's brother used perpetually among his friends to signify "giving their full potential to something". The rap duo has made songs on romance, politics, Indian society and the education system, and their lifestyle.

In 2017, they signed to the independent music label Azadi Records. After releasing their final project Lunch Break with Azadi Records in 2023, they departed from the label and found their own independent label, DL91, in 2024.

The two met at Spit Dope Inc., a Delhi underground battle rap league organized by MC Kode and Encore ABJ at Deer Park, Hauz Khas Village, where Calm delivered a freestyle that would capture the latter's attention. After competing in various rap battles and cyphers together, the duo would go on to release "Seedhe Maut Anthem", their first song together as a duo, and the lead single for their debut project, 2 Ka Pahada, entirely produced by Sez on the Beat. In 2017, they signed to the independent music label Azadi Records, alongside Prabh Deep, a fellow member of Spit Dope.

Calm, who previously rapped in English, switched his language to Hindi, when they collaborated with Prabh Deep on the track "Class Sikh Maut Vol.2", which was a sequel to the track "Classsikh Maut", featured on 2 Ka Pahada.

In August 2018, the duo released the track "Shaktimaan", the lead single for their debut album, Bayaan, accompanied by a music video. This was followed by the release of an introduction track, "Kranti", which was also the supposed title of their debut album, before it was changed to Bayaan. Bayaan, produced by veteran producer Sez on the Beat, was released on December 28, 2018, to critical acclaim.

This was followed by various successful single releases and collaborations by the duo, like "101", "Seedhe Maut Interlude", "MMM/Yaad", Saans Le", with many tracks produced by Calm and longtime collaborator and producer Sez on the Beat. Seedhe Maut also collaborated with singer Ritviz on the track "Chalo Chalein" for the Bacardi Sessions in 2019, which received rave reviews. In an interview with The Bridge Chronicle, they even teased a collaboration album with the singer, but it never saw the light of day and was eventually scrapped. They also released the politically conscious anthem, "Scalp Dem" with Delhi Sultanate in 2019, which was well-received for its outspoken commentary on Islamophobia, casteism, hate crime, and mob lynchings, but also received widespread backlash, which resulted in the deletion of the song from streaming services.

After the release of their debut mixtape न in 2021, which featured the commercially successful "Nanchaku" with MC Stan, the duo released their sophomore album Nayaab in 2022, which mirrored the success of their previous album. The album had been in the works for about two years, and was released to critical acclaim. The album's release was accompanied by an Nayaab.World NFT collection.

The duo was selected for the YouTube 2021 Class of Foundry and performed at the YouTube Fanfest India in 2022 and 2024.
