Mordechai Ben David

In April 2017, Werdyger wrote and released a song titled "Boee Besholom" dedicated to the marriage of his granddaughter. The song was sung at the wedding by Werdyger and Lipa Schmeltzer who was one of the guests. The arrangements on that single were done by Eli Klein and Yitzy Berry, a young and popular Israeli musical duo, who then rearranged it for his album, Tzeaka (released in June 2017), as a Jewish Pop/Techno song named "Bo'ee Kallah", which quickly became one of the biggest dance hits of the year.

Then, six years after the release of his last full album, he finally released a brand new album Tzeaka in June 2017. The album features many new hits in different genres and includes guest soloists such Motty Steimetz and Nussi Fuchs.

In 2016, Mordechai Ben David attracted controversy after a video taken at his December 28 concert in Jerusalem, wherein he referred to US President Barack Obama with the derogatory Hebrew racial term kushi, was circulated online. During the concert, Ben David was between songs while performing a song about peace before thousands of people in the Israeli capital when he remarked to the audience in Hebrew, "Do you know when there will be peace? In a few weeks, when there will be a new president in the United States and the kushi goes home." The statement prompted cheers from the audience, which included Jerusalem Mayor Nir Barkat and Interior Minister Aryeh Deri, both of whom had previously criticized Obama and expressed approval of President-elect Donald Trump.

A single composed for the Jewish Holy Days of Awe labeled "Nekom" was released in 2015.

After great success with Kissufim, in February 2012, MBD announced on Menachem Toker Radio Israel that he had just started on a new album, although he did not release information about the type of album.

Another single released was "Yachad Shivtei Yisrael", composed in honor of the 2012 Siyum HaShas.

The album before his most recent one, titled Kissufim, was released in October 2011. This production was said to be his last album, with MBD stating that illegal CD burning and internet downloads were ruining the industry and making albums financially unprofitable.

In 2010, MBD re-wrote his famous English song "Unity", expressing protest of alleged Federal injustice to Sholom Rubashkin in his widely publicized case in the U.S. The song, renamed "Unity For Justice", was performed by MBD together with Avraham Fried and forty famous Jewish singers. An HD Video recording was publicized on a petition website as well as the social network.

In 1999, on a track sung in Hebrew, "Ad Matay" (heb.עד מתי), written by Chaim Walder, Werdyger took on tensions between Israeli secular and religious parties. This dramatic composition expressed a heart-wrenching cry against internal hatred and takes an indirect shot at anti-religious politicians Yossi Sarid (Meretz) and Tommy Lapid (Shinui) by rhyming their surnames into a phrase depicting "the flame of hatred [lapid lit flame] which leaves no remnants [sarid lit remnant]".

MBD released a single track in 1996, named "Chevron Always And Forever" (heb. חברון מאז ולתמיד), protesting proposed Israeli concessions over Hebron under the Oslo II Interim Agreement.

1994's "Yerushalayim We Will Never Leave You", recorded in Hebrew and English, protested the intent of dividing Jerusalem under the Oslo I Accord.

In 1986 MBD's quasi-rock beat "Jerusalem Is Not For Sale" spearheaded the Haredi opposition to Mormon missionary practice in Jerusalem. The lyrics read "You better run for your life, back to Utah overnight, before the mountain top opens wide to swallow you inside." as well as "The wars, the pain, brought masses returning, back to their roots more than ever. The leftists fiercely fighting truth, dampening the sparks still burning. So wake up my friend, this is the very end, the arrows are pointing our way!"

In 1984 and 1985, MBD's songs "Hold On" and "Let My People Go" focused on the Jewish refusenik plight behind the Soviet Iron Curtain. While "Hold On" expresses hope, "Let My People Go" specifically calls for "support and pressure" to free Anatoly Natan Sharansky and Ida Nudel from Soviet captivity.

MBD's style has been an inspiration to many Jewish singers over the past decades; following his genre are famous headline singers such as Avraham Fried, Lipa Schmeltzer, and Yaakov Shwekey, as well as some of the younger stars like Benny Friedman, Simcha Leiner, Levy Falkowitz and Shmueli Ungar. Together with well-known producer Sheya Mendlowitz, Mordechai produced the first solo recording album of singer Avraham Fried entitled "No Jew Will Be Left Behind" (with songs composed by Yossi Green and the Zimriah Orchestra arranged by Marty Lewinter) in 1981. During that same year, Sheya was involved with the production of two of Mordechai's releases, "Mordechai Ben David Live" (his first live album) and "Memories", written in memory of Mordechai's mother, and featuring songs composed by Yerachmiel Begun (of Toronto and Miami Boys Choir fame). In fact during the following few years, Sheya & Mordechai jointly produced a number of hit albums together including "Mostly Horas" (1987), his own album "MBD & Friends" (1987), "Yisroel Lamm & The Philharmonic Experience" (1988), and "25 Years of Jewish Music" (1988). In addition, Sheya went on to produce both Mordechai's "Simen Tov -Keitzad" (one of the first ever Jewish music "single" releases) (1989) and "The Double Album" (1990).

His wife, Esther, is the daughter and sister of hazzanim. His brother-in-law is Cantor Ari Klein, who in the past recorded a few albums of his own. And his cousin, Shmilu Rosenberg of Canada released two albums back in the 1980s, a comeback album and an appearance on an all-star album in the 1990s.

Mordechai Ben David May be considered a pioneer of contemporary Hasidic song. He started his musical career in the early 1970s, a time when Hazzanut was the main source of recorded music in Jewish Orthodox circles, with very few solo singer performers. Two notable singers who preceded Werdyger were Bentzion Shenker and Shlomo Carlebach, who had started a genre rooted in Hasidic and American folk song in the early 1960s.

Mordechai Werdyger (born April 16, 1951) is an American Hasidic Jewish singer and songwriter popular in the Orthodox Jewish community. As the son of famous Cantor David Werdyger he is known by his stage name Mordechai Ben David (Hebrew: מרדכי בן דוד ‎, lit. 'Mordechai, son of David') or its initials, MBD. He is known as the "King of Jewish Music" and has released over 30 albums while performing worldwide. He has headlined the popular HASC and Ohel charity concerts for almost two decades.
