Blochead here!
From what I've noticed, most post-punk bands eventually go towards the direction of electronica. And I still think Intimacy is a great album, (probably because I'm a big Blochead) but not as intense as Silent Alarm. They also just released "Intimacy Remixed" which even transmits a more Electronica flavor.
But overall, Silent Alarm is still my #1 for me. Their B-sides and their old stuff rock too.
