Frum music is going through more of a renaissance than a demise. Youtube is full of new songs, music videos, and clips from simchas, which makes it possible to enjoy much more of the Jewish music “world” than was previously possible, when all you could do was buy CDs and go to concerts.
Some of my favorites:
Freilach Orchestra – they’ve been getting better and better as they matured as musicians. Nachman Dreier (guitar) and Avrumi Schreiber (drums) are particularly good.
Malchus Choir: a Chassidishe choir – I know nothing about them but it appears they are from Israel. Check out their songs, “Zechor” (don’t know where it’s from) and “Beshoh”, which is a cover of Shwekey.
There are a bunch of great clips of Motti Steinmetz singing classic yiddish and chazzonish songs with various men’s choirs.
Lots of “highlights” from weddings with Shloime Daskal, Sruly Werdyger (there’s a great clip of Sruly Werdyger and the Shira Choir with Yanky Briskman (one man band) and Shloimy Cohen (saxophone – I think he played a lot with Evenal); if you search -Yisroel Werdyger second dance- it should come up.
And the above is just my taste – I’ve watched the videos I mentioned dozens of times. There are also a ton of Yehuda Green, Eitan Katz, etc. type videos from live kumzitzes etc. or more traditional chassidish singers at weddings, chuppas, events, etc.
Jewish music is something that people like to kvetch about for some reason. Generally, it’s people who like Carlebach forcing themselves to listen to MBD so that they can rant about it self-righteously. But in the internet age, it’s crazy for someone with a modem to claim that “modern offerings” are worse somehow than what came before.
