Watch Steve Vai Talk Riffs, Gear, Led Zeppelin on 'My Favorite Riff with Nikki Sixx'

Yesterday, former Mötley Crüe bassist Nikki Sixx sat down with Steve Vai to talk riffs, gear and Led Zeppelin on his series, My Favorite Riff with Nikki Sixx.

Vai also tells Sixx some anecdotes about his time working with Frank Zappa, discussing both an instance in which he transcribed one of Zappa's famously lewd stories into a guitar piece, and how Zappa would push his bandmates into challenging, uncharted musical waters.
