"Fever" is a song by Americanhard rock band Aerosmith. It is from the band's massively successful 1993 album Get a Grip. It was written by Steven Tyler and Joe Perry and is the only Tyler/Perry song on Get a Grip written without the aid of "song doctors". The song is the fourth track on Get a Grip, and is a hard rocking song, running four minutes and 15 seconds. The song reached #5 on the Billboard Mainstream Rock Tracks chart and is one of seven tracks from Get a Grip to make a chart appearance on any chart.
The song seems to be about having a good time, and how the band members, especially Steven Tyler, have abandoned drugs in favor of sex and other enjoyable things in life, with lyrics such as "the buzz that you be gettin' from the crack don't last, I'd rather be OD'in on the crack of her ass."
The song features heavy guitar interplay by Joe Perry and Brad Whitford, a fast-paced drum beat and bass rhythm by Joey Kramer and Tom Hamilton, and loud and varied singing by Steven Tyler.
Brooks' country rock-generated version featured altered lyrics, describing a rodeo star addicted to his profession (e.g., "He's got a split finger wrap and his rope's pulled way too tight / He's got a lunatic smile 'cause he's really drawn deep tonight"). The cover was included on his album Fresh Horses. That album's second single, it peaked #23 on the U.S. Billboard Hot Country Singles & Tracks (now Hot Country Songs) chart and #2 on the RPM Top Country Tracks charts in Canada. Brooks also recorded the song on his 1998 Double Live compilation.
