Never heard any of them ... so what makes them so good? A picture isn't always worth a thousand words
Yes, it was rather rude of me to dump and run on these, but the titles are live links to Amazon, which describe these better than I can (I always seem to get it wrong). Here's some from the links:

Alaska! - Rescue through Tomahawk:

Amazon.com
Rescue Through Tomahawk plays like gimmick-free active rock of a variety that bands from Led Zeppelin to Crazy Horse might endorse—the common thread being a certain heaviness of spirit and a whole lot of thrashing.

Jets Overhead - Bridges: (Go to their website and you can download the entire CD)

Customer Review:

This is a great new full-length from Victoria's newest batch of rising stars. Layers of keyboards and percussion are drenched in sonic guitar feedback, offering a throwback to classic albums by the Who and Radiohead.

Silversun Pickups - Carnavas

Amazon.com
If the idea of basement tapes made by Billy Corgan and Doug Martsch appeals to you, say hello to your new favorite band.



Sorry I'm just cutting and pasting, but I'm heading out for a week of vaca and I felt the urge to post these recommendations.
