In June 1974, Thin Lizzy were auditioning for a new guitarist and a try-out for Robertson was arranged. Aged 18, Robertson was taken on along with Scott Gorham on the other lead guitar. The two lead guitarists provided a critical part of Thin Lizzy"s signature sound, referred to by critics as their "twin guitar attack". During his time in the band, over the course of 5 albums Robertson contributed a substantial share of songwriting, sometimes collaborating with frontman bassist/vocalist Phil Lynott who was the primary songwriter for the band. This Cd contains new material from Brian Robertson.
