If you are reading this, you most probably are aware of what to expect. I got this on vinyl (on the Mulligan label I believe) around 1976/7, and it just knocked me sideways.
From the outset (the intro to "The Kesh jig"), the Bothy Band just come out like bare knuckle fighters, hardly stopping to take breath, the changes of tunes and tempo; swaying and ducking and diving, and delivering knock out music all the way through. Each member, and you most probably know who they are, deliver a raw energetic, turbo charged, enthusiastic, and often copied but never bettered style of traditional Irish music. All of the Bothy Band recordings are superb, but I think that this, their first, for me at least, has the most dynamics.
(Also worth a very good mention is a new group called "The Bonny Men". I would stick my neck out and say that I think they come a very close second to taking up where the Bothy Band left off. Check them out.)
