  • Cypress Hill and the London Symphony Orchestra will perform "Black Sunday" at the Royal Albert Hall.
  • The collaboration has been 28 years in the making following a 1996 episode of "The Simpsons."
  • Wednesday's performance coincides with the album's 30th anniversary.

It's taken almost three decades, but Cypress Hill and the London Symphony Orchestra will take to the stage on Wednesday for an orchestral rendition of the "Black Sunday" album, which features the hits "Insane in the Brain" and "I Wanna Get High."

The one-off gig at London's Royal Albert Hall was sparked by a joke in a 1996 episode of "The Simpsons" titled "Homerpalooza." In the episode, Cypress Hill mistakenly booked the LSO for a performance, "possibly whilst high."
