How Time Passes is the debut album by trumpeter Don Ellis recorded in 1960 and released on the Candid label.

[1][2] Scott Yanow of Allmusic states, "Trumpeter Don Ellis' initial recording as a leader (and first of four small group dates from the 1960-1962 period) found him stretching the boundaries of bop-based jazz and experimenting a bit with time and tempo...

Although these musical experiments failed to be influential (Ellis himself went in a different direction a few years later), the unpredictable music is still quite interesting to hear".

[3] The Penguin Guide to Jazz award the album 3 stars.
