Israeli documentary film "Aviv" was released which focused on Aviv Geffen's life. The film premiered at the Bangkok International Film Festival. In 2004 the album "Blackfield" was released which was a result of the collaboration between Geffen and Steven Wilson of Porcupine Tree. Its followup Blackfield II was released in early 2007, followed by the live DVD Blackfield: Live in NYC later in the year. Both of the Blackfield albums spawned several hits, notably "Blackfield", "Pain" and "Once". A third album, entitled Welcome to my DNA was released in March 2011, in which most songs were written by Geffen. It also contains a renewed version of the track "Zigota"" () from his album Memento Mori. In 2006 Geffen's 11th album Im HaZmán ["With Time"] was released. The theme song is a cover of a French chanson by Léo Ferré, which indicated matureness and sobering from the clichés that he symbolized in his initial years. Most recently he compiled a 2CD/1DVD live album, simply titled Live. Lately, Geffen declared himself radical left. After releasing two albums with Blackfield, Geffen announced in November 2007 that he was recording his first English-language studio album. In January 2008 his single 'End of the World' charted at number one in Poland and he performed at Bush Hall in London on the 31st. He released a single (Silence) at the end of 2008 and is touring throughout January 2009, with dates in Kraków, Berlin, Hamburg, Cologne, Amsterdam, Munich, Paris and London. In June, he announced that recording had begun at Sarm West Studios, with Trevor Horn producing and Steven Wilson and Mike Garson featuring on the album. These sessions led to his debut English-language album, Aviv Geffen, released towards the end of summer 2009. The debut single released was 'It was Meant to be a Love Song'. In March 2011, Blackfield's third studio album was released called Welcome to my DNA. 2013 saw the release of "Blackfield IV" with contributions of several guest vocalists. Beginning in 2012, Aviv Geffen served as one of the four coaches on the Israeli version of the vocal performance competition show The Voice Israel. Geffen spent most of 2015 recording the upcoming fourth Blackfield record, still with involvement of Steve Wilson who obviously took over some guitar and vocal duties, although he had announced in 2014 that he had to stop from being part of Blackfield due to lack of time.
