[2] He has played multiple instruments on his tracks including electronic keyboards, guitars, bass, synthesizers, drums, piano, assorted percussion, trumpet and saxophone.
[citation needed] Both Tennant and fellow Pet Shop Boy Chris Lowe admired Orlando's sound and productions – "Passion" by the Flirts, being a particular favorite.
[citation needed] Orlando decided to produce a Pet Shop Boys album and released their first two earliest 12-inch singles including the original 1984 version of "West End Girls" and "One More Chance".
Orlando and the Pet Shop Boys recorded twelve tracks together, most of which never saw release, including the original versions of "It's a Sin", "Opportunities (Let's Make Lots of Money)", and "I Get Excited".
Orlando's songs frequently deal with philosophical themes such as "Try It (I'm in Love with a Married Man)", which was given a contemporary twist when it was re-recorded by Pet Shop Boys in 2003 (see Disco 3).
