Rush - The Analog Kid. That song probably took the longest of any to go from "it's okay" to "fucking masterpiece"
Must be a in a weird key or I misheard something the first half dozen times.
There are only a few songs I get a massive shot of adrenaline when I play. When those synths come in and it's time for the guitar solo I get this incredible-hulk-like burst and I can somehow play lead guitar at ridiculous speed. Alex is faster than Petrucci easily on that song because he is not playing some shit where every finger just happens to be in the perfect place for speed. Nope, Big Al doesn't cheat. Weird ass scale where all the notes are ridiculously hard to access and 64th's at 220bpm? No problem for Mr. Lifeson.
