Meet the Band

Rich Hammer


Rich started playing professionally in 1979 with The Johnny Lang Band, playing traditional wedding music and old-time standards throughout the Chicagoland area. A few years later, in 1983, Rich joined "The Keystones" and performed as a house band 3 times a week, 5 sets every night. During his time with this band, Rich developed his rock-solid chops and became well-versed in all the 1950’s through 1980’s rock hits, Motown, British Invasion, as well as country and blues. The Keystones and Croozin' the Loop bands joined forces at the end of the 1980's and established Croozin' the Loop, which soon became one of the area’s premier classic rock bands. Highly sought after, Croozin' the Loop performed well over a thousand shows during the next 15+ years. After a short hiatus, Croozin' the Loop re-established itself in 2011, and has continued rockin' the Chicagoland area ever since!


Joanne's lovely voice and keyboard artistry bring a special dimension to the band's sound. Her singing style covers a wide range including Janis Joplin, Patsy Cline, Joan Jett, and Linda Ronstadt. Joanne has loved piano since taking lessons at an early age. After  taking classes at the Old Town School of Folk Music she was newly motivated to continue pursuing her interest in music, and subsequently played with several Chicago-area bands before joining Croozin' the Loop in 2016. Joanne also enjoys songwriting, and has released a CD containing several of her original songs, available on ReverbNation (

Joanne and Al also perform together as an acoustic duo they call "The Jetset", and have also written and released a number of original songs together! See their page at

Tommy Frentzel


Tommy was born and raised in Wisconsin. (He proudly proclaims, “Yes, I am a Cheesehead!”) He moved to the suburbs of Chicago in the 70s and soon began his musical career playing bass and guitar. As a founding member of the country rock group "Deadwood Express", Tom played the Chicago area and southern Wisconsin until 1986, going on to play in a number of other bands performing classic rock at local festivals, clubs, and special events. In 2004 Tommy teamed up with some fellow music lovers to form the group "Roy and the Orbitz", where he played guitar to songs from artists such as Roy Orbison, Elvis, Buddy Holly, The Beatles and other greats from that era. In this, his latest adventure, Tommy has returned to his roots as bass player and vocalist for Croozin' The Loop!
