The story behind Logic Bomb
Logic Bomb grew out of Sweden’s early Goa-influenced forest-party culture in the mid-1990s. Johan Krafft and Jonas Pettersson were among the young Swedish producers drawn into the new music arriving through Goa and the European psychedelic network. Their project history quickly became intertwined with Hux Flux, making Logic Bomb a good example of how fluid the Scandinavian production community was before artist identities became firmly separated. When Krafft travelled, Pettersson worked with Dennis Tapper and Jonas Bergvall in the formative Hux Flux circle. Logic Bomb later re-emerged, with Bergvall also appearing in accounts of the revived project.
That history means the name cannot be reduced cleanly to a fixed duo or trio across every period. The core catalogue, however, is clear. Headware arrived in 2000 on Spiral Trax, Unlimited followed in 2002 on TIP.World, Sonic Algebra in 2007 on Solstice Music International, and The Grid in 2011 on TIP Records. Logic Bomb’s sound is exceptionally controlled. Where some Scandinavian progressive music emphasized minimalism and smoothness, Logic Bomb kept a harder psychedelic edge: precise drum programming, crisp synthesis, sharply defined effects and arrangements that could be intricate without becoming chaotic.
The 2000s catalogue overlaps with Full-On in energy and function, but the project’s roots predate the mature Full-On style and are better understood as part of Sweden’s transition from Goa into modern Psytrance. The 2022 release Dreams, shared with the related Logic Flux identity, reconnected several strands of this history and explicitly carried the legacy of Dennis Tapper. It should not be treated as a straightforward solo Logic Bomb album, but it shows that the project’s network remained creatively meaningful long after its most famous 2000s records.
Origins of Logic Bomb
Logic Bomb began in the mid-1990s with Johan Krafft and Jonas Pettersson after Goa-derived trance reached Sweden’s forest-party scene. Some databases use 1998 as a formation year, but the project’s own history places the origins earlier, so “mid-1990s” is the more defensible description.
The early years
The project’s early history overlaps directly with Hux Flux. Pettersson worked with Dennis Tapper and Jonas Bergvall while Krafft was away, and later accounts describe Logic Bomb being revived with Bergvall involved. That fluid personnel network is part of the history , not a contradiction to be flattened into a single permanent lineup.
How the career developed
Headware (2000) established Logic Bomb internationally, followed by Unlimited (2002), Sonic Algebra (2007) and The Grid (2011). The catalogue moved from early Swedish psychedelic experimentation toward a very polished, technical 2000s dancefloor sound. Dreams (2022), jointly branded with Logic Flux, revived the network around Pettersson, Krafft and the late Dennis Tapper in a memorial and collaborative context.
Logic Bomb sound
Logic Bomb is precision Psytrance: tight bass, clipped percussion, clean transients, carefully placed effects and psychedelic detail controlled with almost engineering-like discipline. The project can overlap with Full-On, especially in the 2000s, but its identity is generally less anthem-driven and more focused on technical movement and rhythmic tension.
Place in psytrance history
Logic Bomb is important to Swedish Psytrance because it links the formative forest-party generation, Hux Flux, Spiral Trax and the later international TIP network. Its catalogue helped establish the highly engineered Scandinavian strand of modern Psytrance without simply following the smoother progressive route.
Connections and influence
Hux Flux and Logic Flux are closely related but separate projects. Dennis Tapper and Jonas Bergvall belong to the wider personnel history, while Johan Krafft and Jonas Pettersson are the clearest founding core. Spiral Trax, TIP.World, Solstice and TIP Records map the project’s changing label context.
Logic Bomb today
The release activity continues and publicly maintained, but the exact current live lineup is not consistently documented. The safest description is intermittent/legacy-active rather than implying a fixed touring membership.
