Boom Crash Opera are an Australian pop rock band formed in late 1984. Initially based around the songwriting partnership of Richard Pleasance and Peter Farnan, the band was later joined by Dale Ryder (vocals), Peter ‘Maz’ Maslen (drums) and Greg O’Connor (keyboards). Pleasance developed tinnitus from constant exposure to loud live music and left in 1992 to pursue a solo career as an artist and producer. O’Connor departed in 1994.

Current line-up includes Dale Ryder (vocals), Peter ‘Maz’ Maslen (drums), Peter Farnan (guitar) and John Favaro (bass).

Their highest charting albums are Boom Crash Opera, These Here Are Crazy Times! and Fabulous Beast. Their top 20 singles are "Great Wall", "Hands up in the Air" (both 1986), "Onion Skin" (1989) and "Gimme" (1994). In the United States "Onion Skin" reached No. 8 on the Billboard component chart Modern Rock Tracks. Australian musicologist Ian McFarlane noted that the group had a "strong visual image and the uncanny ability of its principal songwriters to pen catchy, commercial songs ensured a string of successful releases".
