OP video sounds like heavy Gadd influence, big phonic kit definitely have Billy Cobham/Simon Phillips vibes, of course later years lots Buddy. He can completely play the history of the set, when left foot clave was the big trend he was doing that. Underneath it all is some Jack DeJohnette undertones in alot of concepts and of course the Tony stuff that almost everyone stole. Then he got into Indian, particularly south Indian rhythmic concepts. But also begs to ask, who is Steve because he tends to play trends or imitate very well. Some of the early Journey stuff pretty amazing and by the 2000s he became a technique guru and in the end it still sounds very much him, no matter the influence or imitation at that time. I thought he stole the show in the Burning for Buddy take that sounded like 'Steve Smith' and not an impersonation of anyone else...just a very complete performance that understands the tradition and hints at his bop concepts, killer technique and just fresh idea phrasings and insane forward momentum on that groove...would definitely listen to this track over any Buddy version. A unique drum journey (pun) for sure, I can't think of a more well rounded player honestly.
