Two enchanting voices, one stunning sound. Think Katherine Jenkins, think Eva Cassidy, think Norah Jones. Then think twice! Indigo May have been described as "the best kept secret in classical crossover". Two former members of the acapella group The Swingle Singers who reunited in 2017 to form this duo.

During the 2020 Covid19 pandemic we decided to adapt The Prayer so that we could invite tenor Shanul Sharma to sing it with us. We loved it so much that we included it on our new Christmas album 'Christmas Harmony' as a bonus track.

Experience the spine-tingling blend of two radiantly pure voices that create one phenomenal sound. The best kept secret in classical crossover!

Four ex-Swingle Singers reunited for a special recording of 'The World for Christmas' written by Anders Edenroth of The Real Group.

Classical crossover duo, Indigo May, are pleased to announce the release of their new single ‘Believe’ on 1st November which is taken from the new album ‘Christmas Harmony’. All proceeds from the sales of the single will be given to Barnardos. A donation of £1 will also be made from each sale of the album. The single and album are available on all major music download platforms.

We recorded Adagio a while ago, but during the Covid19 lockdown we decided to invite the Welsh poet and author Mari George to adapt the English lyrics to Welsh. She did a great job! The track was then recorded and mixed during lockdown. This is an Italian / Welsh adaptation of 'Adagio'. It had it's radio premier on BBC Radio Cymru's Bore Cothi. #2voices1sound #IndigoCrossoverDuo

This was Indigo's collaboration with Rhiannon Williams during the Covid19 lockdown in 2020.

Indigo created this new arrangement of Ebben because they wanted to perform is with a contemporary twist. George Gurette Music produced the fabulous orchestration.

This is our medley of Welsh, Irish and Scottish folk tunes. Enjoy.
