Sunday night in Jerusalem, Yerachmiel "Rocky" Ziegler and Aaron Razel celebrated the release of their collaborative album "Raza D'Shabbos" (The Secret Of Shabbos).
Here's a sneak peek with a video of their song "Shamor v'Zachor."
Here, Rocky plays at the debut of the Tapu'ah Nights Melaweh Malkah concert series last summer.
A few weeks later Aharon Razel made an appearance at Tapu'ah Nights, as well. His set begins at the 1:11:50 time marker.
