This is the one that got me into Costello. I remember hearing a couple tracks from This Year's Model before this and being underwhelmed, but after listening to Imperial Bedroom, I not only loved it, but could suddenly get behind everything he had recorded up to that point.
"Imperial Bedroom" was EC's "Sgt. Pepper's." The whole is greater than the sum of its parts. One of those albums that works from start to finish better than as individual tracks (although "Man Out of Time" is a masterpiece).
