"Metal Guru" is a song by the British rock band T. Rex, written by Marc Bolan.

I have codes where people ring me at certain times.The backing track for "Metal Guru" was recorded during initial sessions for The Slider between 8-12 March 1972 at Strawberry Studios, Chateau d'Herouville in France.

At that point it had a stripped-down acoustic arrangement, with massive overdubs of electric guitars, orchestra, and backing vocals by Flo and Eddie added a few weeks later in London.

Demand for T. Rex product was so hot at this time that two Fly repackages, a double set of Tyrannosaurus Rex's first two albums along with a greatest hits titled Bolan Boogie, both also topped the UK Albums Chart at the same time as "Metal Guru", the latter staying at the summit for four consecutive weeks.

Roy Hollinghurst of Melody Maker gushed "swishy, dizzy, and full, and what's more it's 1972 and there's an idol there for idolising".
