Being a hardcore MG/MGB fan, I must point out to you that Weapon is by Matthew Good, not the Matthew Good Band
The former has one album, Avalanche, which you should go out and buy asap, or at least download the tracks Avalanche, 21st Century Living, and While We Were Hunting Rabbits. But buy it
MGB is a whole 'nother barrel of monkeys. They produced 4 albums and three EP's: Last of the Ghetto Astronauts, Raygun (EP), Underdogs, Lo-fi B-sides (EP), Beautiful Midnight, Loser Anthems & B-side Rarities (EP), and the Audio of Being. You'll get conflicting opinions on which album is the best, but it tends to be a toss up between Beautiful Midnight and Audio of Being.
Tracks to download (and I'm assuming you've heard nothing by them): Hello Time Bomb, Apparitions, Prime Time Deliverance, Load Me Up, Strange Days, Carmelina, Advertising on Police Cars, Sort of a Protest Song, Jenni's Song, Going All the Way, and Running for Home, just to get you started.
