Sebastian Ahrenberg, better known as Seba is a Swedish drum and bass producer and DJ Seba is also the owner of Secret Operations, a drum and bass record label.
Seba's first professional release was Sonic Winds, a collaboration with Lo-tek on LTJ Bukem's Good Looking Records in 1995. The duo released Universal Music on Good Looking, after which Seba went on to produce a string of solo releases on various Bukem-owned labels.
In 1997 Seba created a night club named Secret Operations in the basement club Tuben in central Stockholm. Two years later Operations released Case One, a CD compilation of works by Seba (under the pseudonym Forme) and other artists.
From 1999 to 2003, Ahrenberg has released a number of mostly house music works on the Swedish Svek label attributed to Seba and Forme. He has also joined with Jesper Dahlbäck (aka Lenk) for the collaborative house music effort known as Sunday Brunch. The two would release a number of tunes on vinyl as well as full length CD entitled No Resistance in 2002.
In 2002, Seba began releasing drum and bass records again. For the first time on the Secret Operations label as well as various others. While no longer under Bukem's eye, Seba's music retained its deep atmospheric sound while sometimes adding a more aggressive edge not often heard in his earlier works. Operations first release was Pieces, a collaboration between Seba, Lenk and an uncredited Robert Manos as vocalist. Manos had previously recorded with the duo for Sunday Brunch, but this was the first of many times he would join Ahrenberg on a drum and bass project.
In 2004 Seba joined forces with drumfunk all-star Paradox, and the two put out a large number of albums from 2004-2006, with 2005 seeing an especially large amount of releases. A compilation of their work during this time was released on the CD Beats Me in 2006. Vocalist Robert Manos also contributed his talents to a number of works during this time frame.
