I got the "Boston Edge" CD from John's website. It seems the perfect combination of folks, with Joe Derrane on button accordion and Seamus Connolly on fiddle, but the track that is a McGann mandolin solo is sublime among the sublime.
John also plays some nice mando accompaniment on a couple of other sets, tho he mostly plays (lovely!) guitar on this album.
Five stars. OK... seven stars!! <GG>
Thanks, John, Joe, Seamus, a wonderful recording!!!!
