Sharing a love for music – and head-banging – two Israeli and Palestinian rock bands have joined forces to take a “message of coexistence through rock’n’roll across Europe,” The Guardian reported on Monday. The Israeli band “Orphaned Land” and Palestinian group “Khalas” both believe that music is above politics, religion and conflict and should bring people together.

At its core, the Latin Alternative Music Conference is a gathering of dedicated underdogs, rallying behind music that envisions a polyglot, multicultural, border-hopping 21st-century culture but faces stubborn barriers, in the United States, of language and radio formats. The term “Latin alternative” makes room for pop, indie-rock, electronica, hip-hop, punk and hard rock, all loosely connected by a willingness to push past divisions of genre and geography.
