Kalfa released a double album about six months ago in which he hosted the best singers and composers in Jewish music. The last single he released before Purim, "Al Ninisim," in which he hosted Gad Elbaz and Ari Lesser, became a hit that was played a lot.
The new song was recorded at Supersonic Studios by the talented Amit Golan, who also produced the song (and put on tefillin at the beginning of the video).
