I found Lumi to be good, but not great. The earlier Vesala, the better. I recommend "Nana"; "Satu"; "Twet" (under Stanko's name), "Hot Lotta" (with Brotzmann!!); etc.
And those early Juhani Aaltonen albums with Vesala were real kickers!!
Really looking forward to this Mike Osborne Trio release in March, on Cadillac! (I cannot get the pdf link on the bottom of the thread to work, though):

While I love Bob Wills to death, there's really no better homage/cover/whatever-you-call-it than the very excellent Pine Valley Cosmonauts salute to him. It's a 5-star gem of an album.
