What's it like to be strapped into the space shuttle waiting for the "Countdown" and then the "Liftoff?" On this killer release, Mark tackles John Coltrane's "Countdown" chord changes with his own melody "Liftoff", based on that chord sequence. Jimmy Heath says "It's harder to play than 'Giant Steps'!" Mark also introduces his new instrument, the "baritone guitar" on 2 tracks. With 8 consecutive #1 CDs on National Jazz Radio, this is expected to make a showing to match his previous efforts. A must for serious jazz guitar fans and jazz enthusiasts.
