This is RIDICULOUS! Major respect to guitarist Travis Simpson, who put together every single Megadeth song into one chronological medley -- in just one take.

Megadeth's discography of 14 studio albums begins in 1985 with 'Killing Is My Business… and Business is Good!' and has progressed all the way to 2013 with 'Super Collider.' Megadeth have been rocked with the sudden departures of drummer Shawn Drover and guitarist Chris Broderick, but according to bassist David Ellefson, Megadeth is far from done.

For now, Megadeth boast a grand total of 160 songs, and Travis Simpson found a way to connect them all for a smooth medley. What makes this video all the more impressive is that guitarist didn't have much room to work with, as he plays each track in chronological order.

The entire video lasts nearly 20 minutes, and with Simpson tackling both simple and complex guitar work, there's plenty of room for mistakes. Despite the challenge (and switching between three different guitars), the musician nails it all the way from 'Last Rites/Loved to Deth' to Megadeth's cover of Thin Lizzy's 'Cold Sweat.' To top it all off, Simpson fades out while jamming 'Kill the King.'

Check out the mind-blowing medley in the clip above!
