Julian Jumpin’ Perez, who was the first on-air personality hired when Entercom launched its classic hip-hop format on WBMX 104.3-FM in 2018, continues as one of the “BMX Four” mixers from 10 p.m. to 2 a.m. Saturdays. But he’s no longer hosting middays or evenings full-time. Perez, a veteran of Entercom Top 40 WBBM 96.3-FM in the ’90s and a founding member of the B96 Street Mix, also was part of the “Hot Mix Five” on the original WBMX in the ’80s. Look for 104.3 Jams to make adjustments to its air shifts after the start of the year. Until then, music in middays and evenings will air without hosts, according to program director Todd Cavanah. https://www.robertfeder.com/2020/12/02/robservations-wbbm-newsradio-hosts-25th-annual-good-neighbor-radiothon/#more-27734
