In his latest episode of Time Crisis on Beats 1, Vampire Weekend’s Ezra Koenig interviewed an odd assortment of guests. First, Ezra Koenig, co-host Jake Longstreth, and comedian/Time Crisis Family member Jerrod Carmichael, interviewed the composer of the original “Reading Rainbow” theme. Steve Horelick, a composer for TV and video games, produced the 1981 song alongside his wife Janet Weir and Dennis Neil Kleinman. “That opening synth was made on a very rare module by Donald Buchla,” Horelick explains. “I just picked a bunch of notes that sounded good and used the randomizer.” Elsewhere on the show: Koenig talked to Kid Rock’s son, Robert James Ritchie Jr., about working at the Apple Store Genius Bar. Listen to the full episode here.

In the previous episode, Koenig improvised a Nirvana version of a “$5 footlong” jingle; he also half-joked about performing an 8-minute version of “Cape Cod Kwassa Kwassa” at future, no-setlist Vampire Weekend shows.
