There are at least six artists named Ahab;

1) Ahab is a German funeral doom metal band founded in 2004 by Midnattsol guitarists Christian Hector and Daniel Droste. The band is named after Captain Ahab, a character in the 1851 novel Moby-Dick by Herman Melville. Along with its name, the band also draws thematic and lyrical inspiration from Moby-Dick; some songs even feature direct quotations from the book.

Near the end of 2004, with one song already written, Christian Hector and Daniel Droste decided to form a band and recorded their first single, The Stream. On 15 April 2005, after several months of rehearsing, the band's first demo, The Oath, was released. The demo was limited to 30 hand-numbered copies and contained the band's first song, "The Stream", as well as two new songs and an outro track. Nearly a year and a half later, The Call of the Wretched Sea, the group's first full-length album was released on Napalm Records with the help of Stephan Adolph and session drummer Cornelius Althammer.

After the release of The Call of the Wretched Sea, the band played some few gigs in Europe. In 2008, shortly after playing at the Summer Breeze Open Air metal festival in Dinkelsbühl, Germany, bassist Stephan Adolph left the band due to "personal differences." He was quickly replaced by Stephan Wandernoth, a member of the band Dead Eyed Sleeper to which the drummer, Cornelius, also belongs.
