In 2005 Petersen ventured for a solo career starting with his debut hit single ‘Munyaule’ which featured General Ozzy and later that year named his first album Munyaule.

In 2007 Petersen released a new album with producer Ben Blazer title Bobojani

In 2012 Petersen was working on his new album which was the much anticipated album titled Job 13 – 13 (which included songs like Amakwebo mu church, Oxygen featuring Shadaya Zaher, Bvuto La Fwaka & Munyaule Continuously) that was delayed to be released, but the further delays saw him releasing a 22-track compilation titled Stoga Compilation: Tiger Revolution, before the album drops.^[3]

In 2015 Petersen produced his fourth album King Solomon^[4] and also features Afunika, Flexville Marley and Nameless from Kenya. Songs like Kalukobo, Ba Zesko, Boma Ni Boma and Gile were favorites on this project.

In 2018 he produced, recorded and released his sixth' studio album titled Spartacus. Nifola 4 Pin, Ups and Down, Mbambo, Munyaule Pachi Corner, Mankwinya and many other songs composed this masterpiece.

The next and 7tg album for 2022 is titled Apocalyto (Money and Morality). Bwana Ni Munthu Nae, Ma Stylo, Bude, Sample and many are songs building this lovely project.

Music and society

Petersen's reaction of politicians was not entirely unexpected. Pressure also came from some church leaders that took great exception to Munyaule, a song that out-rightly euphemised sex like no other musician has ever done in Zambia.

Petersen used the visibility Munyaule had brought him to highlight several injustices he saw in Zambian politics and the society it breeds.

Petersen did not spare the church with a background in the church, Zagaze recounts in his song Amakwebo Mu Church, the travesty that seem to have engulfed the Zambian church. In his song Amakwebo Mu Church Petersen visits a church after a long time only to find that the church has now become a market place, selling everything from houses, to cars, and music albums. He then requests, that "Messiah bwelelanso ukwapule nafuti … ama kwebo mu church yafula" which means Messiah come back on earth and come Whip again.... Cause business activity has increased in the church. The message in Amakwebo Mu Church is quite appropriate for the Zambian church, particularly the Pentecostal church that seem to be experiencing a serious identity crisis.

Music and politics

Petersen's prolific criticism to the politicians that had moved to ban his 2005 Munyaule. In the Job 13:13^[3] song Zagaze stated that the parliamentarians had better things to do in parliament than debate his songs. Calling politicians as "ba mwankole wearing black suits",(pied crows) he called out their hypocrisy about targeting his Munyaule songs when they themselves had absolutely no morals. The same politicians who were pontificating about morals were "corrupt thieves, selfish and wife batterers.”

In 2013, he collaborated with PilAto on a single entitled BUFI a highly politically charged song that labeled the late President Michael Sata a ‘Father of Lies’.^[5] The song got a negative feed back from the supporters of the ruling party.^[6]
