With the exception of the last track, all the other soloist on these selections are alive and out there playing today.
#1 Bucky was identified by Jim R.
#2 It is a male and his main instrument if alto sax. He filled some big shoes when he was asked to join a band in the mid 70s.
#3 This one, as with number 2, the flute is not his main instrument. His is tenor sax.
#4 Joey DeFrancesco was identified, the guitarist is still not guessed. I would look at who is in Joey DeFrancesco band today.
#5 This hint will give it away, but I am going to give it. Think of Ponce de León.
#6,#7 I am give these away with this hint. These two tenor players are a year apart in age and both older than anyone on this forum.
#8 This one, Bobby Hutcherson was identified. I don't know if anyone knows who the trombone player is. He was new to me, but very skilled. The tenor player is from Chicago. The piano player, who is the lead of this band wasn't born in the US. The trumpet player is from California. Bass and drums, don't solo, but both musicians are big name musicians.
#9 One of my all time favorite piano players. Like 6 and 7, he is older than anyone on thus forum.
#10 This band is from Europe. The group's name was derived from an American Mime Troupe that was touring Amsterdam back in the 1970s. At least that's what their web site states.
#11 This guitarist and pianist are from France.
#12 This band is from Italy. I guess this hint is not much help.
#13 The tenor player was identified as Frank Wess, the vocalist sang in a well known big band/orchestra.
#14 The Great Guitarist. This should be enough to get it.
