You might want to visit http://www.dancemusicproduction.com/ - they have an extensive range of (paid) in-depth video tutorials for EDM as well as forums. I have not tried any of them myself, but they seem to get a lot of positive feedback and they do look interesting. 
 
You'd also do a lot worse than reading the electronic music forum on Gearslutz here: http://www.gearslutz.com/board/electronic-music-instruments-electronic-music-production/
 
As well as browsing through the KVR forums: http://www.kvraudio.com/forum/
 
Of course you do get a lot of the usual arrogant know it alls on Gearslutz especially, but nonetheless there is a wealth of electronic production info to be had from those forums. 

I find a good resource for EDM production tips are forums that focus on individual genres. They can be a little fanatical but tend to be useful

When I first read this thread I misinterpreted it (assumed "electronic" meant DAW). For SONAR, the Matrix View is probably the "go to" for dance music creation. NI's Maschine would be very helpful to fire off the matrix though (which I do not own, since this is not my cup of tea). I did, however demonstrate the Matrix View to friends by recording a dance mix while they watched... just grab loops, through them into the matrix and fire them off while recording. For live performance can do the same easily. The Matrix View is very conducive to this method of music making/playing.

Personally I find the matrix view is useless and it's not a magical solution to making edm .
The matrix view is very non intuitive . It's good just to launch loops and one hits.
sonar not being gapless really makes the matrix view useless compare to abelton live. I would never use sonar live. Ever!
But you can use the matrix view for stuff like crash cymbals , backing loops .Something you need to trigger loops with .
Personally I just add my stuff into the time line . The Matrix view is just a half baked idea such as beatscape.
Some people find a good use for it .but it's not a magical solution to making edm. It's just another tools set at your disposal ..

Although I am sure good results can be had with matrix, I would bet that most EDM creators opt for track or prv or even the step sequencer. EDM has a wide range from what sounds like blips and pops to complex orchestra sequences. The matrix seems to appeal to a small niche of creators that would use primarily loops. I would reccomend watching videos of people making edm in various software. Computer music magazine usually includes video tutorials (often done by some name figure) and is heavily geared towards edm. Although none of these tuts use Sonar, the techniques usually are applicable. Obviously the ableton ones will be hard to emulate but the tuts using logic cubase or reason will be pretty easy to transfer

I make electro music and to be honest I've never even touched the Matrix. I have no idea how you'd make a decent track together with that, unless you just want to put together a mish mash of prepackaged loops. I can see how it would be useful in a live performance, but believe me there are no EDM producers out there arranging commercial music with the Matrix. Making electronic music is a very time consuming and intricate task which involves rolling up your sleeves and getting into the PRV on a note by note basis, not to mention the insane level of parameter automation going on. If you listen to a track like Red Knob by Siriusmo you can hear how much attention to detail some producers put into their music. Way above and beyond just triggering loops. 
 
Maybe I should have a play with it though, after all I have it!

Sharke..I keep telling myself I will do that, but I have not formed a system in my head that would lead to better results. I suppose I could change my mindest about matrix to see it more like fl studio where patterns are stacked. Perhaps program parts in loopable patterns and drag to matrix but it seems redundant. In any case I stand by my opinion thay the only guy making edm with matrix is the guy at the demo booth

+1 about the matrix. Actually, you can see that even most of the Ableton Live EDM production tutorials in YouTube are using the Arrange (i.e. track) view, not Session (matrix) view.

Gavin, why not check out the song forum?  There you can find numerous examples of electronic music done on Sonar, as well as plenty of other genres.

I'm disappointed that MP3 tagging has made 'Electronic Music' synonymous with EDM.
 
I've been composing electronic music since 1979, but nowadays I have to call it 'Experimental' or 'Avante Garde' or 'Garbage' or whatever.
 
But, anyway, the DAW is not the issue - it's all in your head.
