Shrimp Boat Back in Chicago, Prekop formed the band
Shrimp Boat, which was active from 1988 to 1993.
The Sea and Cake After Shrimp Boat dissolved in 1993, Sam Prekop and Eric Claridge formed the Sea and Cake, and recruited
Archer Prewitt and
John McEntire. In April that year, Prekop performed with
Aerial M in Toronto. In 2005, ''
Who's Your New Professor'' featured drummer Chad Taylor and cornetist
Rob Mazurek (both from the
Chicago Underground Duo), bassist Josh Abrams (Sticks & Stones), and the Sea and Cake bandmates Archer Prewitt and John McEntire on guitar and drums, respectively.
Old Punch Card (2010) primarily featured modular synthesizer. Released in 2015,
The Republic further explored the emotional possibilities of the modular synthesizer. The first nine tracks (all named "The Republic") were assembled as part of an art installation by the artist David Hartt also called The Republic. He then released
Comma (2020). It was created by using modular synthesizer, drum machine, and additional synthesizer. In 2022, he released a collaborative album with John McEntire, titled
Sons Of. Inspired by live performances with
Laraaji, he created
Open Close (2025). ==Personal life==
