We know you've been waiting for this one since last summer! Caspa's debut on Youngsta's ridiculously on-point Sentry has been one of the most requested releases in a very long time. Hot on the heels of releases by dBridge, Nomine and Akcept, the Sub Soldier comes in hard with two absolute burn-ups...

'Gutter Riddim' is a stately spacious construction where every weighty element is carefully considered and plays a key role in the momentum. Tightly sprung tension buzzes through it with high voltage as Caspa lays down some of his darkest designs to date. 'Hot Head' hurls us even deeper into the shadows. A true teaser piece, the first bass line is a staccato stab that gives you just enough time to settle into the groove before the real big-balls bass line comes hurtling out of nowhere.

Rewind every single time, this has been causing uncut mayhem for the few DJs lucky to have it early enough. Timelessly gully and a perfect way to kick the doors of 2018 in. As those who were at Sentry's first anniversary at Fire earlier this month will corroborate: London's heart rate is pounding away at 140 again, some of the most crucial bass music is coming out of the city and Sentry, Youngsta and Caspa are slap bang in the heart of it. The wait is over... Enjoy.
