Remember when the 2AM and 2PM boys were on Mnet’s “Hot Blood“? We don’t really remember either, but 2009 turned out to be a big year for the resulting idol groups of that “Hot Blood” project!

At the year-end music festival, the SBS “2009 Gayo Daejun,” these hot-blooded guys explained to us what showmanship is.

2AM performed a joint stage with Davichi, singing “Friend’s Confession” and “8282.”

2PM then had a number of performances, including the first ever live performance of “Tired of Waiting,” a robotic soldier remix of “Again & Again,” and zombie-tastic “Heartbeat.” Girls Generation(SNSD) and 2PM also had a special dance stage to “Be Without You” and “Duran Duran.” Check out that boobi-boobi dance (Korean term for “grinding”)!

See all the performances for yourself! Also be sure to check out the 2PM “You’re Beautiful” parody which was also broadcast during the music festival!
