Time moves in spirals. It took 20 years for Hyperdub to release a jungle album, finally converging with the most important sound of its prehistory.

South East London's Tim Reaper, and Kloke from Victoria, Australia are two big guns from the new wave of junglists.

On Reaper's relentlessly hyperactive label Future Retro, a torrent of releases have helped provide the ammunition to rejuvenate that most precious of pirate radio and sound system styles, Jungle from the period 1993-95, that abstracted elements from dub reggae through to techno, riveted onto a finely chopped and accelerated breakbeat undercarriage.

`In Full Effect' is the intention and the title. It's energetic, exciting and extremely fun.

Its 8 tracks provide a window onto some of the duo's recent collaborations that precision-tool and mix up the best ideas from the period for a new generation of ravers.

For those there the first time around, this album is flush with moments of deja vu.
