Flight of the ConchordsDuff McKagan’s column runs every Thursday on Reverb. He writes about what’s circulating through his iPod every Monday.Clutch, “Mob Goes Wild”: Clutch are the type of band that you need never worry about being a “late-comer” to. They simply play a timeless style of dirty boogie-rock that is fad-proof, if you will. “Mob Goes Wild” showcases these guys’ marriage of killer groove and humor, all wrapped up in a knuckle sandwich!Flight of the Conchords, “Too Many Dicks (On the Dancefloor),” (I Told You I Was Freaky): A couple years ago, I was introduced to the music of FOTC through their HBO series. I bought their first Sub Pop CD sometime later that year. With the release of this newest record, FOTC have somehow found a way to elaborate on the kooky style that they alone invented.Minor Threat, “Betray,” (Out Of Step): For those of you who are sick of it all and want to break the windows and smash the state, may I suggest this song by the most excellent Minor Threat.
