Getting discovered thanks to a YouTube clip in which you sing a song in a taxi at the request of the cabbie: the kind of thing that just can happen these days. And it did happen to Irish singer-songwriter David Keenan, who was soon being compared to greats like Nick Drake and Tim Buckley. That doesn’t happen unless you are a troubadour with depth, expressiveness and a great sense of tradition. Keenan – who grew up surrounded by the work of great poets like W.B. Yeats and Oscar Wilde – most certainly is; not for nothing did someone say his music sounds like it could have been recorded in 1895, 1941 and 2028.
