A few months ago I heard a CD from Rav Shmuel. I put it aside as a Matisyahu copy-cat but now I am reconsidering. The Weekly Forward had an article about his hit, Protocols, which is popular on YouTube. The song has an interesting history--he wrote it in response to anti-Semitic heckling at a perfomance.
It examines stereotypes, misconceptions, and more using humorous lyrics and cartoon graphics.
The graphics help the song achieve its intended result of bursting stereotypes--so it might not work as well with just audio.
Check out Rav Shmuel's website and blog for more about him.
Let me know what you think.
