Only 18 years old when he joined Thin Lizzy, guitarist Brian Robertson was part of the group's twin guitar tandem (along with Scott Gorham) that helped establish Lizzy as one of the world's top rock acts in the '70s. Born in 1956 in Glasgow, Scotland, Robertson spent eight years learning classical piano as a youngster before switching over to the guitar. Just as he entered his teenage years, Robertson began playing in several different local Glasgow bands (one of which, Dream Police, would later evolve into the Average White Band). Lizzy was auditioning for a new guitarist in June of 1974, and a try-out was eventually set up for Robertson, after a mutual friend of the six-stringer who happened to also be a roadie for Lizzy gave him the heads up. With the try-out being in London, Robertson left Glasgow with little money in his pocket and just his guitar and a pair of drumsticks, figuring that if he didn't land the gig, perhaps he could try out for a drumming position in another band. But Robertson didn't have to worry for long, as he got the gig with Lizzy. Soon after he joined, Lizzy welcomed another guitarist, Gorham, into the fold as well, which would lead to the duo developing what would become one of Lizzy's musical trademarks, twin guitar harmonies, which would be copied by numerous future groups (Iron Maiden, Def Leppard, etc.). To finetune their sound even further, both guitarists also played the same guitar make/model, Gibson Les Pauls.
