Swiss-Swedish songwriter and guitarist Sol String's second album takes his music to new heights. Eleven new songs takes you from straightforward rock tune 'Love' to the jazzy 'Awake at Night' with some unexpected Italian rap lyrics over to a Deodato tribute and a Steely Dan-ish groove 'So Much Fun'. Sol has on occasions mentioned that he feels all the best rock music was made before 1980. Listening to String Theory, you will find out why, but you will also be amazed at how well he has managed to combine the essence of the 70's with sounds and styles of the early 21st century. This is not just music for the middle-aged but for everyone with a foot in classic rock and cross-over music. Vocals by Johnny Vitale, Susanne Hederoth and Sol String. Brilliant lead guitars by Sol String.
