The old KMFM 96.1 was indeed a classical station that either switched to B/EZ or added it to certain dayparts. I can't remember the whole story about how it became KSLR, which ultimately ended up at 630, where KMAC was. Seems, though, like KMFM might've been owned by a church when it ran the classical and easy listening formats.
My old history notes...
Signed on in 1964 as classical KMFM. Initial calls were KZFM, but KEEZ 97.3 filed a challenge with the FCC over the closeness of the calls and the calls changed to KMFM 5/14/1964.
Formats...
9/82: Following sale, KMFM became contemporary Christian/religious KSLR "Son Light Radio."
Following another sale, contemporary Christian KSLR signs off late 1983 and went briefly silent. While off the air, KSLR changed calls to KSAQ in December, and the KSLR calls were picked up by KMAC 630. The KSAQ calls and “Super Q” handle were used in the 1970s on 100.3 (now **KCYY**).

January 1984: After being silent for two months, the new owners returned the station to the airwaves as top 40 KSAQ “Q96.” Initially, the format was adult-leaning as some harder rock songs were excluded, but it evolved to top 40 “Hit Radio Q96.” In December 1986, KSAQ began simulcasting with co-owned KSJL 760 and re-imaged as “Super Q.” The simulcast split in October 1988 when KSJL flipped to SMN’s Z-Rock network. KSAQ returned to the “Q96” branding. It would evolved to a rock-leaning sound by 1990. Top 40/rock aircheck I recorded from 8/23/1990:

4 February 1991: With no AOR in the market after KISS 99.5’s format flip to oldies in July 1990, top 40/rock KSAQ flipped to rock "96 Rock” to fill the gap.

In March 1993, rock KSAQ changed to adult R&B, with SMN’s The Touch urban AC programming filling overnight. The adult R&B format moved from sister KSJL 760, which flipped to sports and talk via LMA with news/talk WOAI 1200. KSAQ picked up the KSJL-FM calls in May.

4 September 1998: Adult R&B KSJL-FM became top 40 "Mix 96.1.” The former adult R&B format and KSJL calls shifted to rimshot KTXX 92.5 Devine TX (which had upgraded from 92.1A to 92.5C2) and simulcast on KCHG 810 Somerset TX to extend market coverage. KSJL-FM changed calls to KXXM on the 21st. KTXX/KCHG picked up the KSJL calls. KXXM rebranded as "96.1 Now" in 2017.
