Well if it's older artists that I only discovered this year, here's three:
Reno's Men--check out Glen Jones' archives for interviews and in-studio performances as well as CDNow for "Steroe Slide"
Starky--I'm torn on this band. They have one album, "Mirror, Signal, Manoeuvre" that rocks from end to end. It was produced by Rob Younger. Their other efforts pale in comparison.
Sour Jazz--Every album this band has done sounds like the fourth Arista Iggy album...seriously, it is a dead ringer for "New Values"...drop dead Iggy vocals married to drop dead Ivan Kral guitars. Oh yeah, there's a killer trombone thrown into the mix.
And for new re-releases, this came out about a month ago:

Australia's Hitmen...Radio Birdman alums, soon-to-become Hoodoo Gurus. 2 CD set contains the original debut plus first two singles, plus scads of demos and live cuts, with ferocious Blue Oyster Cult, Stooges, MC5, Roky Erickson, Magazine, etc. covers.
