The Hebrew word “shalom” means peace, but it’s also a greeting and sometimes a goodbye. For Roni Nachum, a young producer from Jerusalem, “Guest Service Shalom” is one hell of a hello. His vinyl debut, which so skillfully walks between deep house moods and techno’s edges, arrives care of the shrewd A&R work of Nitzan at Fine Art Recordings. It’s also backed by a superb, decompressing remix by Mark E.
