tape echo

Tape echoes became commercially available in the 1950s.

The first tape echoes became available to musicians in the early 1950s; since the 1970s they have largely been replaced by first analog and then digital delays.

Mr. Smith, a veteran of the octet that Mr. Brubeck led in the 1940's before he formed his quartet, was wired for taped echoes, which gave the group the effect of an additional instrument.
