As a Prog old-timer, I often find today's "retro"-Prog a little forced: modern musicians trying too hard to recreate a vibe that died essentially 30 years ago. While Transatlantic is a bunch of accomplished musicians with their own styles and sensibilities, they can still fall into the same trap with a listener concentrating more on influences than on the music itself - and The Whirlwind has them all ....
.... that said, it is a fine album: assured songwriting, melodies with lots of variety; elegant, creative arrangements; rousing performances, excellent musicianship; well recorded: the suite [not a single piece!] mostly flows pretty well from pastoral beauty to vamped-up rock to rustic acoustic to grandiose ballad; intensity shakes hands with gentleness, fluctuating moods; lengthy instrumental sections liberally dispersed. Trewavas' energetic basslines are superb; heavy, powerful; I find Portnoy a trifle too hyper at times on drums, and some lyrics become a trifle preachy, but that's a relatively minor quibble.
My only previous Transatlantic record was debut SMPTe which left me unconvinced; a typical supergroup that flattered to deceive; but nine years later they sound much more `together' as a true band working in harmony, with subtle interplay and sensitivity: this is key to my enjoyment of this record and whether I will still feel as positive about it in a year's time, but I think I will! The Whirlwind is a classy, well-balanced record: the best retro-Prog album I have heard for many years; it knocks spots off most neo-Prog output!
PS - the extras on disc 2 [special edition] are fully realised recordings; OK in themselves but they don't really add any value unless you are a committed Transatlantic fan.
