After playing together as a family band for a wonderful run of 8 years, the Amber Waves Band is no longer performing officially together as a group. The older two are well into their college studies, with other two soon to follow, looking towards their own unique future goals.

Thank you to everyone who supported us along the way! We had a memorable time throughout our travels, seeing the beauty of this country and meeting many wonderful people. We will be leaving this website up for a time to serve as a memory of our music, a place to host our old recordings, and for any future promotional needs a family member may require.


Taking audiences on a delightful tour of modern and historical folk sounds, the Amber Waves Band, featuring the Costello family, brings an exciting mix of acoustic music, including the sounds of Celtic, Old English, Colonial American, Bluegrass, and Gospel, as well as their own original music.

Starting in 2008, this young family band has grown from a living room band to a full time family band of professional entertainers. Today they travel throughout the country in a converted school bus, playing and singing for audiences of all ages.

The band consists of some amazing young instrumentalists, including identical twins, Alexandra, using both finger and flat-picking guitar, and Kaitlin, who combines Scruggs-style playing with her own style of folk and Irish banjo, laying it down once in awhile to strike a bodhrán. Also included is their younger brother Sean, with phenomenal fiddling, well beyond his years, and little sister Mary, joining in occasionally on fiddle and singing with a darling voice that charms any audience. Parents join in as well, with Michael on the bass, and Cheryl on the flute, fife, or mandolin.

Though the instrumental skills has certainly gained them attention, the family is probably best known for their stunning vocals. Alex shines on stage with powerful lead vocals, often joined in haunting harmonies by Katie. Sean, with a keen ear and full of excitement, sings lead as well as harmony. Cheryl, a former opera-singer, brings in a rich lead and helps out with the harmonies, and Michael brings in the lower sounds with a smooth baritone. Young Mary joins them occasionally, singing out as though she was born for that very purpose!

Through their music, the Amber Waves Band takes audiences on a journey through time, exploring melodies through the ages and telling stories of our musical past, merging together the sounds of traditional American Folk, Old English, Irish, and Bluegrass music, as well as original compositions.
