In 1993 Sumon started to work on his first solo project "SUMON O' AURTHOHIN". One of the most exciting parts of the album was the song with eight of the finest heavy metal guitarists in town! There were twenty eight guitar/bass solos in that song, and the name of the song was 'Aurthohin'. The history was made!

Though work on the album was done long time ago, it was finally released in Eid of 1997. People liked the album which also got positive review from the critics.

Sumon was planning to form a band. Titi & Sentu of 'Faith' came along to help him. With some other musicians Sumon started performing under the name "Sumon O' Aurthohin", same as the album. The band was born!

Titi & Sentu had to leave the band in October'97 as they had to make time for their own band Faith. Rumie the jubilant drummer left his band 'The Trap' & joined. Sumon changed the name of the band to 'Aurthohin'. Zubair & Adnan left the band few months later. Until now, the band's sound was more 'unplugged'. To bring more variety to the sound, Shovon came in as a guitarist & vocalist.

Meantime, After playing for a year in 'Maqsood O Dhaka', Piklu left the band & also joined Aurthohin in 2000. Aurthohin started the recording of their debut album in April. Shovon took a break from the band for educational purposes. Tonmoy also left the band. Ponir, who used to be the guitarist of 'The Gnomes' of Niloy Das, joined Aurthohin. Ponir left the band. Rassel, the vocalist/guitarist of 'Winning' joined the band in 2000, Aurthohin's debut album 'Trimatrik' had been released. Album was a big hit! Sumon's name got enlisted in the Warwick's 'Famous Users' List'. He was the first asian musician who got into that list!

Rumie & Rassel left the band. Shuvo.... the ex-drummer of Jolly Roger/ Phycho Death/Death Row joined the band end of 2001. Aurthohin started the work of their 2nd album on the 17th of November & released it on the 10th of December 2001 under the label of G-Series. Apu, the keyboardist of 'Triloy', started playing with the band as a guest member. 2nd album 'Biborton' was released! One of the best selling band albums of the country!

Imtiaz of 'Kronic' joined the band as a guest vocalist & Rhythm Guitarist. Aurthohin has released their 3rd album "Notun Diner Michhile" from G-Series on the 29th November 2001 which includes a 28 minute long progressive metal song (the longest song of Bangladeshi band music history)

Imtiaz & Apu left the band. Aurthohin decided not to take any more guest members. Shishir of dNA joined the band as the new keyboardist & guitarist. Suddenly, the band faced the biggest problem ever! Sumon got ill. Doctor told him that he won't be able to sing like before. Sumon had to stop singing most of the metal songs. Aurthohin decided to take a new vocalist. Rafa (the drummer of Kral) joined the band as the vocalist & guitarist. Aurthohin's 4th album 'Dhrubok' got released.

Due to Sumon’s illness the band stopped almost all the gigs. End of 2004 Piklu left the band. Sumon got the affiliation from MTD (Michael Tobias Design).

In January 2005 Sumon’s jaw got dislocated! Doctor told him to stop singing permanently! Chances of recovery were very low! Aurthohin stopped all activities. Sumon & others were planning to disband Aurthohin!!

Suddenly things started to change! Sumon was getting well! Doctor said it was a miracle!

In June 2005 Sumon started to sing again & offered Kamal (Ex-Guitarist of Warfaze) to play as a guest member. Kamal took the offer. A few months later Kamal joined as a permanent member! Aurthohin started to do the gigs again! The band also started the work of their 5th Album 'Aushomapto'... but the band didn't know that the biggest disaster was on it's way! Sumon got ill again! This time it got more serious! Aurthohin stopped almost all the activities again! He went abroad for his treatment. Doctors were suspecting something pretty bad but the grace of Allah, Bassbaba recovered! Meanwhile Shuvo had to leave the band for his personal reason. Rafa took the throne. Aurthohin started to do gigs again. Right now they are working on their upcoming album 'Aushomapto'.
