"On the Threshold of a Dream" is the fourth album by the Moody Blues, released in April 1969 on the Deram label.

The album reached the top of the album charts, the group's first No. 1 album in the UK. It also boosted their American fortunes by becoming their first top-20 album there.

The Moody Blues were an English rock band formed in Birmingham in 1964. The band initially consisted of Graeme Edge (drums), Denny Laine (guitar/vocals), Mike Pinder (keyboards/vocals), Ray Thomas (multi-instrumentalist/vocals) and Clint Warwick (bass/vocals).

Originally part of the British beat and R&B (rhythm and blues) scene of the early–mid 1960s, the band came to prominence with the UK No. 1 and US Top 10 single "Go Now" in late 1964/early 1965. Laine and Warwick both left the band in 1966, with Edge, Pinder and Thomas recruiting new members Justin Hayward (guitar/vocals) and John Lodge (bass/vocals).

The Moody Blues sold 70 million albums worldwide, including 18 platinum and gold LPs. They produced 16 studio albums, six of which made the US Top 20 (with two reaching No. 1) and eight of which made the UK Top 20 (with three reaching No. 1). They were inducted into the "Rock and Roll Hall of Fame" in 2018, for "over 50 years of exhilarating and significant music that has influenced countless musicians and rocked fans around the world".
