Supposedly not one of their best albums of the 70's era, Supertramp's "Crisis What Crisis" looms large in my collection in that it was the album that introduced me to this excellent band. While their sound is anything but current, I don't think anybody could argue with the standard of musicianship, songwriting and production that went in to making their records.
This record influenced me in that it made me realise that there was room for excellent musicianship and prog rock elements in pop music.
Fortunately, I was introduced to this record on tape and was therefore spared the artwork on the back cover. Guys not wearing shirts on album covers was a very 70s thing, in some ways its good that we have moved on since then.
