Any discussion of reggae royalty usually opens with the late Bob Marley, his wife, Rita, and sons Ziggy, Stephen, Julian, Ky-Mani, Rohan and Damian, and daughters Stephanie and Cedella.

When Stephen and Damian "Jr. Gong" Marley take the stage tomorrow, fans will be treated to the authentic Marley soundscape that blends wailing acoustic reggae with touches of the harder dancehall sound.

Damian Marley scored a massive crossover hit with 2005's "Welcome to Jamrock" and its colossal eponymous single, which still gets major airplay. Older sibling Stephen started off with Ziggy & the Melody Makers and has lent his musical support to a number of Marley-related releases. Somalian rapper K'naan joins in for this set.

Fillmore at the TLA, 334 South St., 8 p.m. tomorrow, $23, $25 day of, 215-922-1011, www.livenation.com.
