Edward Nana Poku Osei known by the showbiz name Hammer of The Last Two (born March 27, 1977) is a Ghanaian record producer.

[1][2] He is the founder and CEO of The Last Two Music Group and known for growing Ghanaian Hip Hop or Hiplife artists, including Obrafour, Tinny, Kwaw Kese, Sarkodie, Ayigbe Edem, among others.

The family lived in North Kaneshie and later moved to East Legon, a wealthy neighborhood in the capital in the late 1980s and presently as well.

Hammer was known to drum on any surface available to him anywhere he found himself and was also known to patrol his neighborhood with a boom box sound system while playing loud music with friends.

After the hip-hop revolution, Hammer then became a fan of Special Ed, A Tribe called Quest, EPMD, De La Soul, Craig Mack, Guru, Rakim, Das Efx, Jay-Z, Dr. Dre, etc.

In 1997, as the young Hammer and Way Deep started their music production career, a friend (Edward Adu Mensah) introduced them to Obrafour, a potential rapper with unusual singing abilities and after vigorous grooming from Hammer, his debut album produced by Hammer and Way Deep was released on the Home Base Record label owned by Daniel "Masoul" Adjei and was later managed by Noise Management, owned by Abraham Ohene-Djan in August 1999.

After Obrafour's album, a disagreement between Way Deep and Hammer split the two producers but they have since remained friends outside their production differences and still keep in constant touch.

[6] In 2004, Hammer took up yet another challenge with an artist called Kwaw Kese, an indigene of the ‘Fante’ language who hailed from Agona Swedru in the Central Region.

Within three months of training, Hammer released a single, ‘oye nonsense’ from him which immediately made him eligible for concerts and appearances.

Demand for this artist was so high that Hammer had to release the second single ‘kwakwa” which certified Kwaw Kese as the best ‘Fante’ rapper Ghana had ever seen.

Hammer did not want to waste time on Sarkodie so he quickly signed him for a five-year contract and created spaces on two of Ayigbe Edem’s songs ("u dey craze" and "give it up") to introduce him before the recording of his debut album.

Hammer began his career in music accidentally, when a friend of his (Yaw Opare Anoff, aka Way Deep), a gifted keyboardist at the time encouraged him to take up the career because he realized Hammer had the ability to dissect and analyze music in the most unusual ways as a professional does.

This friend and Hammer then formed a production unit called The Last Two, meaning the only two left to put Ghana on the world map musically.

After Obrafour (who rapped in the Twi dialect, typical of the Ashanti people), he challenged himself by risking the production of albums in other unpopular dialects, musically and made history again with the recording of Tinny, who raps in the Ga language, typical of the people of the Greater Accra Region of Ghana.

The compilation albums include Execution Diary (2003), which was in partnership with Obrafour, Sounds of Our Time (2004), The Crusade of the Lost Files (2006) and the ongoing Evolution Recruits.

As a known perfectionist and a very passionate musician, Hammer's methods of grooming his artists have come into question and controversy but the results of the unearthing of iconic stars seems to shut negative observers up.

At a press conference for one of his artists, Hammer was arrested for failing to appear in court on delay of child support maintenance payments.

Hammer currently lives in his retreat home in the outskirts of Accra, where he is working on his new compilation album as well as new artists Agyekum and Joey B.
