A singer-songwriter who straddles many worlds, Aliza Hava is at once an olah, an expatriate, a peace activist and a Jewish spiritualist. She follows up an acoustic set at Mike's Place in Tel Aviv last week with an 8 p.m. appearance tonight at Tantur (between Jerusalem and Bethlehem), where she'll be joining a full lineup of entertainers for a program entitled "Two People, Two States, One Peace." The gig is part of a multi-day international campaign, with coordinated events in Rio de Janeiro, Boston, Chicago, London, Berlin, Rome and elsewhere. Locally, the event kicks off this evening with headliner David Broza at 5:30, followed by a series of performers that culminates with a set by Jerusalem-based acoustic ethnic groove ensemble AndraLaMoussia. On Saturday, peace-themed movies (including the Oscar-winning West Bank Story) will be screened, with live performances resuming at 6 p.m. The second day's concerts and ceremonies include an 8 p.m. set by Lod-based rap collective DAM. In the past, Hava has played at a World Peace Prayer Ceremony at the Washington Monument, at the U.N. International Day of Peace, and at downtown Jerusalem's activism-themed Daila club, so playing for a global harmony-oriented crowd is hardly a stretch. However, she is still considered an artist who operates largely within the "Jewish music" genre - perhaps because of her lineage as a descendant of 18th century Poland's "Biala Rebbe," Rabbi Yaakov Yitzchok Rabinowitz. "Because I am Jewish, people keep thinking of me as 'a Jewish musician,'" she notes. "But I think that has more to do with society's need to place labels on people in order to understand them. Although my spiritual beliefs do play a role in what I write, I feel that my work goes beyond the barriers of religion to a more universal connection with people from all walks of life." Ultimately, activism is what drives Hava's creative output. "Since I was a teenager," she explains, "I've been performing music that has to do with peace, justice and unity - it's in my blood." Back in New York, Hava has been touring extensively in support of her debut solo album, Rise, a powerful 2006 femme-guitar pop-song cycle that evokes Tracy Bonham and the early Alanis Morissette. She has also been busy composing for soundtracks, developing a series of love songs for a new album and gigging with an ensemble called Neptune's Daughters. But playing shows in Israel remains a priority for her. "It is incredibly important for me to have a presence in America so I can reach a wider audience," she admits, but adds that "it's also important to share the spirit of my music in Israel because it's my home."
