Heads, Bill Charlap. Tails, Brad Mehldau. The title of Coin Flip might be interpreted as references to the output of the heralded piano trios led by Bill Charlap and Brad Mehldau. Addison Frei may not be quite as accomplished as those jazz luminaries, but the album released in July indicates the musician raised in Lawrence, Kansas, is becoming increasingly worthy of comparison to elite pianists. Joined by bassist Tamir Shmerling and drummer Diego Joaquin Ramirez, Frei alternates between evoking Charlap’s mainstream elegance and Mehldau’s piano trio explorations. Coin Flip’s most rewarding moments occupy the sweet spot at the high-flying intersection of the two approaches.
