Kaleidoscope was a Coldplay EP from 2017, conceived as a counterpart to the album A Head Full of Dreams. Its five tracks partly come from the same period: All I Can Think About Is You and A L I E N S were left over from those sessions, Miracles (Someone Special) is a collaboration with Big Sean, and Something Just Like This appears in a live recording with The Chainsmokers. Hypnotised closes the EP.

This edition is a 12-inch.
