Hans Magnus Ryan, alias "Snah", (born 31 December 1969 in Trondheim, Norway) is a Norwegian rock musician (guitar & vocals), known as front figure of the band Motorpsycho.

The ambitious, progressive album Demon Box (1993) gave the band a nomination for the Spellemannprisen, and secured Motorpsycho a loyal group of followers in Germany, Belgium and the Netherlands as well as in Scandinavia.

During his tenure as a core member of Motorpsycho he has delved into a wide array of rock related genres in connection with the band's trademark quest for development.

Likewise his comprehensive ingenuity both as instrumentalist and composer is an integral part of the different soundscapes chiseled out in the trio's relatively vast output since 1991.

Ryan's live improvisational abilities are prominently featured in the band's "Roadworks" series, documenting in concert highlights from Motorpsycho's touring history.
