Z is the fourth studio album by psychedelic rock band My Morning Jacket. This collection features a much spacier and more polished sound than previous releases, making heavy use of synthesizers throughout and incorporating reggae and dub influences. The heavy reverb that was a defining characteristic of the band's prior recordings is largely absent. The songs on the album are more focused and shorter compared to the band's previous albums.
