Roo is back with fast melodic songs, electric flying licks, ambient interludes and a bit of fusion. This darker episode leaves aside the bluesy phrases of Guitar Without a Cause (his 1st album) and will remind of Joe Satriani and Marty Friedman. Recorded with the RooBand (Jaakko Nikko, Juke Eräkangas and Timo Aula), Plectrum Spectrum hosts a guest guitar solo from Mr. Fastfinger.
