Joshua Robert Hampson[1][2] (born 10 June 1965[3]) is an English musician and composer, known primarily as a guitarist in the band Loop, which he co-founded in London in 1985 with his then-girlfriend Becky "Bex" Stewart.

[4] When Dowson left the line-up in 1996, Main became a solo project for Hampson, who then abandoned the guitar altogether, feeling he had taken the instrument to such extremes that there was no longer any scope to create with it.

Between 1999 and 2003, he formed the electroacoustic duo Comae[5] with Janek Schaefer touring in Europe, US, Japan, and released their self titled album on Rhiz Records.

He deactivated Main as a project in 2006, in an attempt to free himself of the restraints of critical and fan-based reviews, that still mentioned the guitar as the focal point of the material, even though he had not used it in many years.

In 2010, Hampson announced that he would be reactivating Main, which along with his solo acousmatic work, he will start performing and recording as a more collaborative process with fellow sound artists.
