Ronald Leon Rakow, the former manager for US band The Grateful Dead, has been sentenced to five years in prison for tax evasion, say US prosecutors.
The 69-year-old was found guilty of evading payment of $2.2m (£1.1m) in taxes to the Internal Revenue Service.
Prosecutors alleged that between 1998 and 2003 Mr Rakow had tranferred assets to accounts held in other names.
US District Judge Margaret M Morrow said Mr Rakow chose to break the law to support his "comfortable lifestyle".
