1. Tom Petrover (Hayehudim)

2. Orit Shachaf (Hayehudim)

3. Harel Moyal

4. Roei and Ron (Synergia)

5. Ivri Lider

Chose them cos Hayehudim have some great songs, same for Harel, Synergia are good all round and well.. you can't not like Ivri

You are an Israeli rock music fan i can see althouughh..harel moyal doesnt seem to fit well..perhaps his second album became more "rockish"? well who cares..as long as you enjoy their music ahh

Yeah I am more into the rocky stuff lol. Downloaded Harel's album ages ago but never listened to it, then I accidentally found one of his videos on youtube and haven't stopped listening to him since
Are there any other rock bands similar to Hayehudim and Synergia that I might not have heard of?

Harel has some nice songs yeah..i would say, just enjoy the best of everything..no need to like only rock music..i like a bit of everything

Hmm similar bands..im not sure..perhaps these are 'soft' compared to hayehudim and synergia, but you can check them out:
Beit HaBubot
Malkat HaPlakat
Knesiat HaShechel

Not sure about these:
Mashina
Emergency Exit

If you cant find them..let me know..ill post some videos and give you some links

I really like Israeli music. My top 5 Israeli popular musicians:

1) Harel Skaat
2) Keren Peles
3) Idan Yaniv
4) Ivri Lider
5) The Idan Raichel Project

Yael Naim and David Broza might make the list but technically I'm not sure either of them count. Rita merits an honorable mention.

There's a music video that's receiving a lot of airplay on the Israeli Movie Channel by a young man playing a Yamaha piano and singing a haunting melody. There's images of dogs in a dog pound intersperced throughout the video. Does anyone know the name of the singer or the song?

Well here is my last list of FAV singer (I won't change again)

1. Shiri Maimon

2. Sarit Hadad

3. Ran Danker

4. Harel Moyal / Harel Skaat / Ninet Tayeb

5. Subliminal

let me add 1 more.....

6. Maya Buskila
