Query: So Glad to Have My Guster Back

I discovered them with Keep it Together--which I loved. Then I went backwards. It's nice to know that Guster hasn't done the same thing. They have grown, matured--musically, lyrically--and I couldn't be happier. Manifest Destiny has a catchy hook, and One Man Wrecking Machine just draws you in from the first note. The Captain and Lighning Rod also have great sound. But nothing can top Ruby Falls, which takes Come Downstairs and Say Hello (from KIT) and escalates the emotion, the drive, and the vocal energy. But overall there is a new-found power to the music, with its rich layers and tones, yet still maintains the vocal harmony we've come to love. Guster is just plain great. Ganging up on the Sun will play on my iPod all summer long--and beyond.
