Ahmad Jamal's final Impulse! date documents his appearance at the 1971 Montreux Jazz Festival. Comprising two epic improvisations, each occupying an entire side of the LP, Outertimeinnerspace is a challenging but deeply rewarding effort that captures the pianist at his most profoundly spiritual, exploring otherworldly dimensions of space and sound. Jamal, bassist Jamil Nasser, and drummer Frank Gant all deliver performances of uncommon intensity, channeling the energy of the audience into music that pulses with life and crackles with inspiration. Both "Bogota" and "Extensions" demand listeners' full immersion, and reward their efforts with music of uncommon daring.
