Aviv Geffen (Hebrew: אביב גפן, born 10 May 1973) is an Israeli rock musician, singer, and songwriter.

In addition to his solo career, Geffen is a founding member of the band Blackfield, he was also the global music director for WeWork.

In 1987 Geffen participated in the amateur film "Hamitpaḥat" "The Handkerchief", for which he wrote and sang the song Ima "Mom".

[2] He had previously advocated that Israeli youth should likewise refuse military service and criticized Israel for being "a paranoid country where people think they always have to be strong.

Geffen performed in clubs with his band HaTauyót ["The Mistakes"] (the Hebrew name is purposefully misspelled in two places).

In 1993, Geffen released his second album, Achshav Me'unan [It's Cloudy Now], which went gold in the same year and expressed his generation's dissatisfaction with the Israeli government.

In his next album, Shumakom [Nowhere], Geffen took charge of the production, albeit with help from Reuven Shapira (as sound engineer), and producer Moshe Levi.

In September 2000, Geffen released his 9th album, Yomán Masá [A Journey's Log], for the first time produced by Louie Lahav, and on a new label – "Helicon".

Geffen collaborated with two notable colleagues – Daniel Salomon (who joined from the Leilot Levanim tour) and Moshe Levi, who was involved in the orchestration.

Geffen had recorded 11 melodic songs, with a bonus track – a tribute to Bob Dylan – an Israeli cover of Geshem Kaved Omed Lipol ["A Hard Rain's Gonna Fall"] (translated by his father).

The album produced three notable hits for Geffen: Uri Ur ["Wake Up"], Tsalakót ["Scars"], and Yoman Masa (together with Arik Einstein).

In 2001 Geffen met and began to collaborate with British rock star Steven Wilson, with whom he created the band Blackfield.

Blackfield combines the musical efforts of both musicians and they perform their own original compositions as well as Aviv's own songs translated into English.

Their fourth release in 2013 saw Wilson take more of a back seat due to his own increasing workload, opting to produce the album and contribute minor writing and recording work only.

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.

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.

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.

Part produced by Tony Visconti and Trevor Horn, the EP features four tracks, includes the lead song Mr Down & Mrs High, with 'Jerusalem', "Highway' and 'When Summer Comes'.

[11] Over the years, Geffen's musical style has been influenced by rock bands like Pink Floyd, U2, Radiohead, Nirvana, and artists like John Lennon and Bob Dylan.
