As you would expect from John Petrucci, this album is a progressive feat. Heavy riffing, stunning leads, and overall great guitar work. This album is his (from my understanding) main solo instrumental album. It's a pretty technical album, but surprisingly has less technical wankery than some of Dream Theaters stuff. This is more natural, and definitely has more emotion in it. This album has a great mix of styles, a huge testament of Petrucci's immense knowledge of guitar playing. This album really opened up my mind to Petrucci.

Suspended Animation is an instrumental album, so no vocals. Instead, I'll base this on how "vocal" the guitar work is, and how much it makes you not want vocals in the song. I was surprised at how emotional/vocal Petrucci's guitar playing is on this record, it's really good stuff. It's definitely up there on the level of guys like Satriani and Gilbert. I'll give it a 10 just because it's that good; you wont miss the vocals at all.
Overall Impression — 10
I haven't heard anything else by him, but I've heard his Dream Theater and Liquid Tension Experiment work. I really think it's as good, if not better. It has all that great guitar work, plus the whole element of emotion that Petrucci is often criticized for "not having". I really like "Jaws of Life", "Glasgow Kiss", and "Lost Without You". Those are the songs, in my opinion, that really show his emotion, style, and diversity. I really can't knock this album for anything really, it's a great record. I would definitely buy it again if I lost it. I'm really happy with what he's managed to do on his own, and hopefully he eventually pumps out another amazing solo/instrumental album in the future.
