THE HIRUDO EFFECT(formerly known as Anti Jap Riot) born in 2004, in the southern Milan. Starting with a 2 man line-up (LELE - Guit & Vox, ALE - Drums), soon they discover a funky attitude, when SADIR enter the band as bass player. When JAP (vox) complete the line-up, with is pure grindcore screaming, the hirudo effect begin to strike: just like an hirudo (aka "leech"), the band start take influences from every kind of music, from hardcore to fusion, passing from grindcore and funky.

As ANTI JAP RIOT, the band release a demo in 2005, including 5 tracks of what they call "Madcore". In december 2005 they have their firs tour experience, about a week between Switzerland and Germany whit SLEDGE HC (r.i.p.), and in october 2006 they've another tour, this time in Germany and Czech Republic, with SUPPURATED and the Czech band SHEEVA YOGA.

In october 2007 the band start thinking about some radical changes, starting with the name: ANTI JAP RIOT became THE HIRUDO EFFECT. Then is line-up's changing time, with the entrance in the band of south milan's porngrinder Mr.CFA, who take care of synth, programming and addictional vocals. At this moment, the band is working on the new tracks and on the live-image as well. The debut of the NEW "The Hirudo Effect" is planned for February 2008.

February 2008 will be the release date of the first full lenght of the band too. "Saziando L'Uomo" (that's going to be the title) will include 14 studio tracks and 11 live tracks, for a complete vision of what the band was from 2005 to late 2007.
