Query: It is the Bonus Disc!

OSI is an interesting side project involving Dream Theater and Porcupine Tree members. Quite honesly, the first dics in this set is the American release of the original OSI album (2003). It is reminiscent of Too- Eistein, but on the BONUS disc you hear this band in heavy prog action! Even there cover of Set The Controls For The Heart of the Sun is EXCELLENT! The book-like case sits very well on your shelf. Awesome spin!
