A great Jewish composer was Nifter today: R' Benny Hershkowitz Zatzal. He is most famous for Ain Aroch- the classic one that was originaly sung by Shtreicher (not to be confused with Baruch Levine's). He also composed Umipnei Chata'einu on Yumi Lowy's album ("Ve'ain ve'ain ve'ain anachnu yecholim, da da da, laasos..."), which was later resung on a Mezamrim album. He also composed, IIRC, Raza Dishabbos, also sung by Shtreicher. He put out his own solo album, but I don't think it ever gained traction.
