Wonky (also known as purple sound, aquacrunk, or lazer hip hop) is a subgenre of electronic music known primarily for its off-kilter or "unstable" beats, as well as its eclectic blend of genres including hip hop, '80s electro-funk, 8-bit music, jazz fusion, glitch, and crunk. It initially emerged in 2008 from the UK's dubstep and grime scenes, exchanging their austere sound for a typically colorful or exuberant style featuring garish synthesizer tones, melodies, and effects. Artists associated with the style include Rustie, Joker, Hudson Mohawke, Zomby, and Flying Lotus.
The "wet and unstable" sound of wonky is often achieved by producing unquantized beats and mid-range basses using pitch bending, mid-range synths, LFOs on lowpassing and highpassing, phasing, and delaying.
Though wonky music is united by the tendency to use unstable mid-range synths, every wonky music scene has its own specific traits in sound. The American wonky "street bass" scene is influenced by broken beat and jazz music and the music itself has an organic feeling, while the Glasgow aquacrunk and Bristol purple sound scenes are influenced by the sound of crunk, chiptune, electro and instrumental grime/dubstep, respectively.
Aquacrunk was pioneered by Glasgow artist Rustie, and features slowed down, low-slung beats influenced by Southern hip-hop with electronic mutterings and morphing basslines.. It is influenced as much by early Rephlex and Underground Resistance releases by crunk artists like Lil Jon or Young Buck.
Purple sound emerged in Bristol in late 2008 out of the splintering dubstep scene and took inspiration from wonky, which it is sometimes considered a part of. It incorporates synth funk from the 1980s and G-funk production from the '90s into dubstep, while also introducing many aspects of grime and chiptune (several prominent purple sound artists cite video game music as a large influence). Purple sound usually includes synths as a main component and avoids the bass 'wobble' and 2-step common in dubstep. The majority of purple sound tracks are instrumental.
