Last weekend, Pharrell used his Coachella set to bring out a slew of special guests like Gwen StefaniSnoop Dogg, Nelly and Tyler the Creator

This past weekend he upped his own ante with surprise appearances from Jay ZUsher and T.I. Check out the above clip to see Pharrell and Hova perform "Frontin," "Excuse Me Miss," "La La La," and "I Just Wanna Love You (Give It 2 Me)." The video is a tad blurry, but if you squint hard enough you can make them out beyond the bevy of camera phones.

For Usher's performance, the two performed the R&B star's "U Don't Have to Call," a song Pharrell penned for Usher's 2001 album 8701. Check out the fan-shot video below, accompanied by requisite deafening shrieks. 

And in case you forgot, Pharrell was also one of the principle voices on Robin Thicke's 2013 mega-smash "Blurred Lines," along with T.I. Shaky video of that performance has emerged too, where they breeze through their parts as if it was their own song. Also, for those Coachella fashionistas, take a tip from T.I.: Grey sweatpants work just fine. 

Pharrell wasn't the only one to bring out blasts-from-the-past. Nas, fresh off last week's Illmatic at 20 onslaught, used his Coachella time to bring out a ferocious Lauryn Hill for the Fugees "Ready or Not" and the Nas/Hill tune "If I Ruled the World (Imagine That)." Compare with the video below:
