While I have purchased and listened to 'Killingsworth' a couple times, I have not had a chance to digest it as of yet. IMHO, the record is much more on the somber/sad side compared to other Minus 5 efforts.
Gone are the Beach Boys sounding records like 'Let the War Against Music Begin' or the hard rock sounds of 'In Rock' but it has a much more country feel to it.
Pitchfork gave it a slightly favorable review overall and there is a story here regarding McCaughey in the Oregon Live.
