F5 was one of the bands former Megadeth bassist Dave Ellefson got involved with following his falling out with his former leader, Dave Mustaine. The band's name was neither inspired by a camera nor by a hi-tech company. It was actually a designation for a top level tornado storm rating. Ellefson, a Minnesota native, would soon recruit Sick Speed's Dale Steele from the same state in 2002 and proceed to record a demo. The bassist had earlier produced demo material for Dale’s band NUMM. A deal with Deadline and Cleopatra would result in the Arizona band's debut, A Drug For All Seasons, to come out in mid-2005.

F5 guitarist Steve Conley was offering private guitar lessons in Arizona at Atomic Guitar Works as of 2008. F5 featured Megadeth drummer Jimmy DeGrasso.

F5 - A DRUG FOR ALL SEASONS - DEADLINE/CLEOPATRA
After three years of coverage and media speculation A Drug For All Seasons is some actual music from F5, the band of former Megadeth bassist Dave Ellefson. It is nothing like his former band. It is nether thrash metal nor deliberately commercial hit single fodder. The vocalist can sing.
Mainstream riffing is not foreign to F5 and the songs here have a lot of commercial potential, yet the album is never out of the hard rock range. The generally short songs on the album are reliable with real soloing, heavy backbone and a hard rocking, if controlled, metallic songwriting. There are also notable slow parts and Eastern medleys which alternate with loud outbursts meaning balanced demeanour in these cases. The singer, Dale Steele, has a slight nasal tang to him, but grunges the songs up more than anything. He certainly can belt it out.
A Drug For All Seasons might be a coincidentally appropriate title for this collection of songs. We will have to wait to see if it has a strong enough pusher behind it though. - Ali "The Metallian"
