In a Metal Mood: No More Mr. Nice Guy
In a Metal Mood: No More Mr. Nice Guy is a 1997 album by Pat Boone in which Boone covers hard rock and heavy metal songs in a jazz/big band style. Boone promoted the album by appearing in leather clothing (and, at that year's American Music Awards, wearing a dog collar). He succeeded in propelling "Metal Mood" onto the "Billboard" record charts (making it Boone's first hit album in 36 years), but it did not please some of his older, longtime fans who considered the heavy metal genre  in bad taste, or worse. The album has since become somewhat popular as a joke gift to metal fans (as often indicated in reviews given to it) although some serious sites have given it good reviews on its own merits. The album featured guest appearances from well-known rock musicians such as Ronnie James Dio and Ritchie Blackmore. In October of the same year, and in a similar vein, Steve Lawrence and Eydie Gormé covered Soundgarden's "Black Hole Sun" in a lounge-jazz style on the 1997 compilation album release, "Lounge-A-Palooza". This idea of giving rock hits  a "standards" treatment was imitated later by Boone's contemporary Paul Anka in the 2005 album "Rock Swings", which also featured Anka doing a cover of "Black Hole Sun".
