I love all his stuff. There was only about 5 songs on this album that I didn't already have, but I went ahead and bought the whole thing, because my recordings are mostly scratchy and low-volume, where these are louder and somewhat remastered. Along with Octa Clark and Belton Richard, he's in my "top 3" favorite accordion players. There is also a new Belton Richard collection album out (both of these came out this year). Out of the 100+ recordings of Belton's that I have, there were 3 or 4 songs on this new collection that I didn't.
I have a Bb accordion made by Harrison Fontenot "Imperial" he made it for Mike Tate. Harrison engraved Mike's name on the bottom of the accordion. I don't know what key it was originally but there's video of Mike playing it on youtube "Café Chaud"
