Liam Tyson (born Liverpool, England), also known as Skin, was the lead guitarist for the now defunct Liverpool band Cast. Since the bands split, Tyson has gone on to play with Led Zeppelin legend Robert Plant in his new band "The Strange Sensation".

Liam also played in the greatly under-rated Liverpool band 'pyramid Dream' who played around liverpool in the late 80's / early 90's, and also performed a short series of concerts in leningrad (st petersburg) in 1991, in a cultural exchange tour organised by Liverpool city Council. The music of this band was a highly sophisticated blend of Pink Floyd style ambience with shades of U2's emotive power and something of the harmonic and melodic subtlety of the Pat Metheny Group, of whom the band were big fans.

Liam did not contribute greatly to the compositions of this band however, his contribution lying in 'total dedication to his instrument'.
