Seasons is comprised of the siblings Mary-Kate Spring, Peter Winter, Mary-Teresa Summer, Mary-Grace Autumn, and Mary-Clare Chun Lee. The Lee siblings seeks to not only pay homage to the rich tradition of Celtic and American Folk Music that they grew up in, but also to treat it as a living, breathing entity that can and should be expanded on. The result is a constantly growing collection of songs that are all at once both fresh and familiar. 
While the instrumentation of the band remains centered around the Celtic Harp and Hammered Dulcimer, over the years the band has widened their repertoire of instruments to include violin, mandolin, guitar, bodhran, penny whistle and piano. 
Seasons has recorded multiple CDs, “Eventide Lullabye” (2006) and “Which Way to Dublin Town” (2009), and also collaborated with Mary-Kate on her solo album “Mirabilis” (2010). In March of 2012, Seasons released "Amhrain," a collection of traditional and original Irish Aires followed by their return to Christmas music with "Joy on High" released in December of that same year. These albums have received recognition in publications such as Musicmaker’s Magazine, Catholic Digest, Christianity Today, and Grapevine Online, and also have been played on regional and national radio. Their song “The Helmsman,” based on a poem by St. Faustina, was selected as one of the songs on the highly anticipated audio recording of St. Faustina’s Diary (published by Marian Press). 
Seasons has performed on both regional and national television, including EWTN programs “Life on the Rock” and “Dana and Friends” as well as on “Fox and Friends” the early show for Fox News. The Lee Siblings have toured in multiple states and countries and have opened for artists as varied as Grammy award-winner Ashley Cleveland, the Celtic-rock band Scythian and Celtic Fiddle Festival. The Lee Siblings have been featured performers at many national music festivals including the LAUNCH! Music Conference and Festival, The Millennium Music Conference and Festival, and The Celtic Fling & Highland Games out of Manheim PA. 2012 saw Mary-Kate win first place in Celtic Harp at the Maryland Irish Fest. 
In 2013, Seasons banded together with two other premier Celtic Acts, The Celtic Martins and Rebel Heart Irish Dancers, to create the stage show “Celtic Celebrations” a dynamic program involving all three acts performing together in an exciting fusion of Irish dance backed by live music. Celtic Celebrations kicked off with a benefit concert for Hurricane Sandy Relief. The concert raised $6,500 for Red Cross Storm aid. Seasons also continued to be a force to be reckoned with in the festival circuit, with Mary-Kate taking second place in Celtic Harp at the CCE Mid Atlantic Region Fleadh, impressing the judges at the CCE All Ireland Fleadh in Derry, and returning to defend her first place in Celtic Harp at the Maryland Irish Festival, as well as taking first place in Traditional Irish Singing. Mary-Grace gained her first festival in victory, taking first place in Miscellaneous Instrument at the Maryland Irish Fest.
From Musical Festivals to Renaissance Fairs, from school assemblies to Six Flags Great Adventure, Seasons strives to share their music where and when ever they can. With their influences ranging from O'Carolan to Yeah Yeah Yeahs, the group creates an exciting and surprising fusion of various Celtic and American folks styles in their original music, resulting in a sound that is truly worth a listen.
