Fast paced instrumental guitar ballad? Know which one I'm talking about?

Okay here goes nothing. There’s this faster paced electric guitar ballad that I think goes back to the early ‘80’s or late ‘70’s. It’s been used in a promo commercial for news stations in Los Angeles in the past, I’ve heard it on the radio, and I’ve seen it used for montages on television. There’s a lot of fast fingerwork, and a mix of pacing, starting slower, then speeding up with more strumming—a cascading, crescendoing, driving rhythm that culminates in some slower fingerwork. Sounds a bit like the old HBO commercial theme from the early ‘80’s. I thought it might be Satriani but I can’t seem to identify the song. Feel like using the word “anthemic” to describe it.
