This afternoon, Alan Adamson, his wife, Ms. Eclectic, and I went to the concert by Tanglefoot, in Clinton of all places. The group is sort of a holdover of folk music from the 60s, with a touch of Celtic and a touch of rock flavour to their music; and everything they sing about is based on Canadian history. Despite its slight anti-American tone, I quite liked their song about Laura Secord. And I also enjoyed the song about the great slide that destroyed the town of Frank, Alberta.
The band members are all excellent musicians, with good voices; and Al, the bass player, has a fantastic voice.
The concert was in a local church, and I'm sure I would enjoy it much more in a cabaret or pub setting. Here is a link to their upcoming concert schedule. They're worth seeing in any venue.
My only reservation was that the instrument volume was too high, relative to the voices, at times, making it difficult to understand the words to the songs at some points. But we all still really enjoyed the concert, and I'd certainly recommend seeing them. The group will be in England while I'm there; I may very well go see them there, too.
Update. Alan's review is more detailed and he has posted a couple of photos.
