Time Machine is a double CD set, one disc of studio material (including four tracks from the long-out-of-print "Joe Satriani" EP) and a disc of killer live versions of some of Satriani's best songs. To hear pieces like "Flying In A Blue Dream" performed live can be riveting entertainment, but it also confirms that these ripping ideas aren't just pasted together--or at least that they're not impossible to execute as one continuous stream of playing. Time Machine makes an excellent first CD for new fans of Satriani instrumental guitar and will give longtime fans some new examples of incredible guitar playing. Instrumental Guitar (Electric (Heavy)/Hard Rock), total running time, 2 hr+ - Joe Satriani @ iTunes!
