Rob Ahlers released his first EP titled Chance alongside the band, The Chance in 1993. Since then, Ahlers has performed with numerous bands, including the band he cofounded in 2003, 50 Foot Wave. He has served as the drummer for 50 Foot Wave since the band's creation in 2003, until their most recent album in 2016.
In 2019 Ahlers assisted musicians Jason Cropper and Brian J. Kenny in forming The Jason Cropper Band. Ahlers performed guitar alongside Cropper and Kenny at the band's inaugural show the same year, and has switched between playing drums and keyboard for the band since then. Additionally, Ahlers performs drums and keyboard on the singles for Cropper's forthcoming album and has contributed in producing the album alongside Cropper, Kenny, Michael James and David Skaff.
Although Rob Ahlers is known for being a percussionist, he is also just as fluent in instruments such as keyboard, guitar, bass, and vocals.
