 In Milwaukee, where he came from, Peter Mulvey was under the tutelage of Willie Porter and then went to the Boston area and spent years busking in the subways, honing his philosophy. The Dreams from Peter Mulvey's album Deep Blue and Jethro Burns with Howard Levy. What a duo. Take the A-Train, written by Billy Strayhorn, of course. That's from an album called From the Vaults, Volume 3, the 1983 Super Sessions.
