"Illusions" is a song by American hip hop group Cypress Hill. It was written by members B-Real and DJ Muggs, and produced by the latter, who used a sample of Gary Burton's song "Las Vegas Tango". It was released in February 1996 via Ruffhouse/Columbia Records as the second single from the group's third studio album, III: Temples of Boom. An accompanying music video was directed by McG.
The song found better success in the United Kingdom, reaching number 23 on the UK singles chart, number 17 on the Official Dance Singles Chart and number 4 on the Official Hip Hop and R&B Singles Chart. It also peaked at number 33 in New Zealand.
According to James Masterton, the song marked a change in direction for Cypress Hill, "being more laid back than anything they have ever released before, so much so that it is almost ambient in tone".[2]
