I give the new Killers album my highly coveted "Presto: Instant Whale Shit" award. Two thumbs way-the-sweet-mother-fuck down.
Nik Bartsch's Ronin late 2008 release, "Holon" is my best-of-08. Though I only recently discovered it. Still, I was skeptical going in, and it just reached out and bitch slapped me all up and down the street. Its got everything going for it that "the perfect" rock album would have, but its fucking jazz. Its definitely going to be a weekly listen for me (at minimum), for a long time.
Right behind that is Ryan Adams/Cardinals with "Cardinology", which has, to me, the perfect balance of immediacy, country tinge, and acoustic rock without over-doing the southern drawl.
Fleet Foxes "Sun Giant" e.p. is great, but not up to the same level as Cardionology. But you can't go wrong for $5.98 for it. Its a no-brainer.
