Intelligent drum and bass maintained the uptempo breakbeat percussion, but focused on more atmospheric sounds and warm, deep basslines over vocals or samples which often originated from soul and jazz music. However, alongside other key producers in the scene, LTJ Bukem, arguably the single most influential figure behind the style, is especially noted for disliking the term, owing to the implication that other forms of drum and bass are not intelligent. From this period on, drum and bass would maintain the unity of a relatively small musical culture, but one characterised by a competing group of stylistic influences. Although many DJs have specialised in distinctive subgenres within jungle and drum and bass, the majority of artists within the genre were and remain connected via record labels, events and radio shows. It is extremely important to note that many producers make tracks in more than one subgenre of drum and bass.
