Runrig first played a number of the songs recorded for
Play Gaelic during their summer 1977 concerts. Audiences, which had been used to the band playing dance music and cover versions, did not initially respond well to the Gaelic songs. Gradually the new songs grew more popular. The BBC had launched Radio Highland in 1976, broadcasting a series of opt-outs from
BBC Radio Scotland aimed at both English and Gaelic language listeners.
Play Gaelic was played regularly by the station, presenter Iain MacDonald recalling that "Runrig were the only people in [the Gaelic music] market who were appealing to anything like a youth audience" and that, as a result, the album "got battered to death", so much so that vinyl copies became unplayable. Although the head of Radio Highland, Bill Kerracher, disliked the album, referring to it as "American music with Gaelic words",
Aonghas MacNeacail of the
West Highland Free Press gave the album a "rave review", writing that he felt the album "thoroughly contemporary" and the band "the first Gaelic rock band". Writing a year later in the
Glasgow Herald, Douglas Lowe described the album simply as "good", although others, including Jim Hardie and Neil Campbell of The Electric Ceilidh Band, reacted less positively to the album. Commercially
Play Gaelic sold 6,000 copies, and retrospective views of it tend to focus on its importance as the first contemporary all-Gaelic album to be considered successful. It has been described as "seminal", Broadcaster Martin MacDonald was "knocked sideways" by the album which he considers was "so completely and utterly different it was disturbing". In
Tom Morton's opinion the album "doesn't sound like rock music at all" and lacks the attack provided by contemporary bands such as
Horslips or
Fairport Convention, but despite its "incredibly dated" sound, highlights the importance of the album and in particular the "power" of the album's closing track "Cum 'ur n'Aire" with its message about the importance of preserving identity. The album's liner notes describe "Cum 'ur n'Aire" as the song that "probably sums up the whole point of the album", A contemporary conversation with Martin MacDonald also stressed the political importance of using Gaelic lyrics, with MacDonald reported as saying that the band did not necessarily need to become overtly political as "you are political by the mere fact that you exist". The album was released at the start of what the
Glasgow Herald later described as "the first true revival in Gaeldom since
Culloden", with the band's music in the "forefront" of a "resurgence in Celtic awareness". ''Play Gaelic's'' liner notes describe Runrig's members as having "always believed that the Gaelic language should progress from its traditional roots and develop like any other significant living tongue", a sentiment which the
Glasgow Herald suggested in 1983 did not "mess about". The Scottish Traditional Music Hall of Fame considers Runrig "an inspiration to a generation of singers and musicians growing up in the
Gàidhealtachd" and that their songs from this era provided music that "young Gaels could relate to", Reflecting on the album in 1983, however, Calum was of the view that because he was "refinding" his Gaelic, the lyrics on
Play Gaelic were "not as good as [they] should be in a literary sense". ==Track listing==
